Devon explains Garthe had been imprisoned with three consecutive life sentences in Africa, and was expected by Wilton and all to never be seen again. He's managed to escape and has settled in Las Vegas. Things get more complicated when Michael learns Rita is also involved with Garthe, and her brother was conducting some kind of investigation on him. Michael uncovers her brother's audio tapes containing information on a place known as "Red Bluff", a classified weapons storage facility deep in the Nevada desert. Red Bluff currently holds a collection of tactical missiles which would be dangerous in the wrong hands, especially a third world nation. When Michael learns Garthe is secretly meeting with an African military general named Tsombe Kuna, the pieces come together. Just how Garthe intends on getting the missiles out of the highly guarded facility isn't certain; that is until Michael comes face-to-face with a massive semi truck known as "Goliath" which is protected with the same indestructible molecular bonded shell technology as KITT. Garthe shows Michael just how unstoppable Goliath is when he lures Michael to a dry lake for a showdown. Goliath clobbers KITT in a collision that nearly destroys him.

In the meantime, Garthe manages to escape and rushes to stop Michael before he can plant a bomb on Goliath. Once Michael is discovered, he is taken prisoner by General Kuna and is forced to watch Goliath smash its way into Red Bluff. A squad of Kuna's soldiers then load the missiles into Goliath's trailer.

Back inside KITT, Michael chases down Garthe to confront him in a final showdown before Kuna can take possession of the weapons.

Michael infiltrates a maximum security prison to spring a convict named Peter McCord, who is terrified to leave the big house, and even turns down his parole.

Fenton threatens to explode a powerful bomb hidden somewhere in the city if McCord is not handed over, but McCord manages to get away when Hunt's agents drop him off for Fenton's thugs. Michael goes looking for McCord and his only lead is his estranged daughter, Lisa, who refuses to even speak to her father believing he murdered her mother Rachel. Once McCord is found, he confronts Lisa and claims his innocence saying Fenton murdered Rachel, who had also been Fenton's lover for a time before the mobster was sent to prison. By the time Fenton was released, he found Rachel and McCord had married and was furious. Now McCord must prove himself to his daughter and help Michael bring Fenton down and find the bomb with only minutes left before detonation.

Strock is also involved in funding a re-election campaign for Congressman Albert Ebersol. In a ravine near the facility, Michael finds the gruesome remains of Amelia's burned out car. KITT determines the car was destroyed by a rocket fired from the air. Devon informs Michael that the schematics are for a rocket called the "Sledgehammer", which is the main armament for an experimental helicopter known as the "SX411". Michael sneaks into the surplus yard and finds the helicopter. He believes the facility is a front for the sale of illegal weapons, and the money is being funneled to Ebersol. The next morning, Devon and the police, raid the facility but find it empty. Strock of course feigns ignorance and there is no evidence to bring him in. Michael's next plan is to pose as an arms dealer to draw out a gunrunner named Kragen who can be linked to Strock. Strock's next move however, is to eliminate Michael and Camela and orders Kragen to use the SX411 to get rid of them.

The Foundation receives a strange phone call from a worker at a wrecking yard who claims the owner is exploiting illegal immigrants as slave labor, and who murdered one who opposed him.

Michael knows Sloate is willing to kill to get Nacinda back, and the situation intensifies once he learns Jennifer has been kidnapped.

Michael investigates a series of cat burglaries, the most recent, the theft of a priceless ruby necklace. The burglar leaves a calling card behind and Devon indicates he was once robbed by a thief with a similar modus operandi named Raymond Fallon; although he was never caught. Devon also mentions Fallon was killed in a plane crash a month earlier so it couldn't possibly be the same thief. This burglar happens to only be stealing from other criminals and they don't report the thefts to authorities. Michael wonders if Fallon taught his criminal trade to someone else and suspects Fallon's daughter, Grace (Geena Davis). Grace admits she in fact trained with her father, but she is not responsible for the recent thefts. Michael soon crosses paths with a trigger-happy police detective, George Barth (Jack Starrett), who when he first found out about K.I.T.T. should've been scared straight, who suspects Grace and is revealed to have personal vendetta against her. He failed at catching her father and now that the master thief is dead, he is determined to nail his daughter in the act. Michael and Grace must now dodge Barth and plan a trap to catch the real thief.

There, Michael meets Carrie Haver, a young woman trying to win a trophy for her deceased father's exotic car, but Carrie is being strongly urged by the show coordinator, Suzanne Weston, into selling it to her. When Carrie's car gets stolen, Michael immediately suspects Weston who has a criminal background, but trailing her doesn't lead to the stolen vehicles.

April restores what is left of KITT and temporarily installs him in a portable television set. While KITT undergoes a personality complex, Michael borrows Devon's Mercedes to look for Randy Merrit, a young whiz kid who Michael suspects to be the hacker. His only lead is Randy's worried mother who explains the boy has had relations with a strange woman named Adrianne Margeaux (Ann Turkel). Later, he learns Adrianne had dealings with George Atherton, a man who was once on the Foundation's board of directors. He learns Adrianne may be using Randy to operate KITT's body and steal Atherton's priceless art collection which is being transported in an armored van.

April and Michael abort a test of KITT's new "pyroclastic lamination" (which will protect him from sustained heat up to 800 degrees), when Devon interrupts and gives Michael a tape recording of a distressed Cajun woman named Lela Callan. Lela is afraid her murderous ex-husband Cray, who has just escaped from a Louisiana chain gang, may try to kill her for testifying against him at his trial. Michael goes to the bayou to investigate and soon meets a reverend who says he sent the tape. The reverend is then shot by Cray and Michael gives chase, but KITT has an unexpected systems malfunction and becomes stuck in the swamp. Michael looks for help but is attacked by hound dogs and taken to a shack where Lela is hiding. Meanwhile, Cray and a gang of criminal bounty hunters begin a manhunt for Lela. With KITT struggling to remain operational, Michael must find a way out of the swamp, which Cray has set ablaze, and rescue Lela who is trapped in a cabin filled with dynamite.

Michael is chasing down a suspect who leads him to an abandoned dam, but the suspect gives him the slip. Michael finds a secret door, but the thug ambushes him and tosses a grenade.

He eventually returns to his old precinct but the cops tell him he's been "dead" for two years. In shock and suffering from amnesia, Michael becomes more confused especially after a driverless, talking car begins following him around. KITT returns him to the Foundation where Devon and April try to explain his past, but Michael refuses to believe any of it and leaves. KITT follows and convinces him to retrace his steps back to the dam. Bombarded with flashbacks, Michael must recall his identity as Michael Knight and find the man who tried to kill him.

Michael goes to a small town to shop for a tuxedo for the Foundation's annual Christmas banquet, but he accidentally hits a Gypsy boy named Tino. He claims to be hurt and Michael begins to drive him to a hospital, but a quick scan by KITT determines the boy is fine and he has a very expensive gold watch on his person. Although Tino denies it, he lifted the watch from a group of men and Michael takes him to the police. The police inform Michael the watch was stolen during a bank robbery and the men are suspects. The crooks are not finished with Tino yet. Fearing the boy can identify them, they try to hunt him down. Michael meets Tino's worried sister Marta and suggests to her that Tino "lie low" for a while at his Uncle Stephano's camp until the cops find the suspects. Marta's devious boyfriend Nick, however, has personal connections to the crooks, and informs them where to find Tino. Marta is disgusted by Nick's betrayal and goes after her brother, warning Michael that he is still in danger. Now he must find the troubled teen before the bad guys do.

A burglar breaks into the Foundation's guest house and murders Charlie Granger who is an adventure writer, treasure hunter, and close friend of Devon's. The killer also steals a treasure map and disappears. Devon fears Granger's daughter, Catherine, may be next since she carries the "key" to the treasure in a locket. Michael goes to the private Woodgrove School to fetch her, but the pompus and arrogant girl refuses to go with him and hardly shows remorse for her father who she doesn't consider a part of her life. Michael resorts to kidnapping and forces her back to the Foundation where he tries to prove she meant everything to her father. Meanwhile, Catherine's guardian, Christopher Stone (Lance LeGault), demands Devon hand her over but he refuses until the murderer is caught. Stone's threats lead Devon to believe he is the one behind the killing and may want the treasure for himself. Elsewhere, Catherine has made contact with Stone, the only person she trusts, but she quickly finds out Stone indeed wants the treasure and will kill her to get it.

A fashion model named Rachel is found dead; an apparent suicide, or so the police believe, however her friend Lauren believes she was murdered and contacts the Foundation for help.

He starts by checking out Chris Carlson, Rachel's boyfriend, but finds him murdered in his apartment. After chasing and losing a suspect who fled the scene, Michael decides to snoop around during a lavish party hosted by Lauren's boss, Bernie Mitchell, who gives expensive-looking, but fake, diamond jewelry to his models. He discovers Mitchell is switching the real diamonds with the fakes after his models return from shoots in Europe and South America. His girls wear them to sneak them past U.S. Customs and Mitchell then sells them illegally to foreign VIPs. Michael guesses Rachel and Chris knew about it and planned a little heist of their own, but Mitchell caught on to their scheme. Michael still needs proof, and after Lauren is dragged down to Mexico City for Mitchell's next sale, Michael heads there and devises a sting operation involving Devon to pose as a buyer for the diamonds and catch Mitchell with enough evidence to bring him down.

Michael goes to Vista Beach to investigate a string of robberies; the most recent hit is an art gallery owned by Marietta Mattheson and her niece Cindy.

Craig has another confrontation with Michael when he shows up at the gallery looking for Ron and harasses Cindy for his whereabouts. Craig indicates Ron's car was spotted leaving the crime scene, but Cindy refuses to believe Ron had anything to do it. Michael eventually finds Ron who swears he's not the thief and fears he's being set up. He has Ron hideout aboard the Knight mobile unit and investigates further. He soon becomes suspicious of a song "Crumblin' Down" played by a local radio deejay, "Handsome" Anson, and realizes the song is broadcast just before each robbery while the cops are busy chasing after the racers.

To avoid further complications, Michael has Christina play along with the ruse while he tries to locate Devon and April.

Michael and KITT find Adrianne's estate where Garthe is holding Devon, April and Dr. Bergstrom prisoner. The duo doesn't get far when they encounter Goliath blocking their path. Veering out of the way, KITT flies off a cliff but is saved by his new emergency parachute, however KITT is disabled in a rough landing. Garthe's thugs soon capture Michael and he's introduced to Garthe's dungeon; a rat infested cell just like the one Garthe was held captive inside of in Africa. KITT is held in a garage with his nemesis Goliath. Elsewhere, Devon, April and Bergstrom rig an explosive to escape their cell, but they are quickly captured again. Garthe reveals that Bergstrom will be "sold" to an interested government and smuggled out of the country via submarine which is waiting off the coast.

Devon decides to bring in Michael Knight (David Hasselhoff) as the test driver.

The Knight 4000 has most of KITT's original features, including a few new and improved systems such as an advanced amphibious mode (which allows the car to ride on water like a speedboat), a virtual reality heads-up display (or VR-HUD, which utilized the entire windshield as a video display), and a microwave stun device that could remotely incapacitate a human target.

Michael has KITT print more copies, sending one with a fake signature to Daniels using her name, and a similar one to the mayor, this time with his name. Following the mayor's limo, they record a conversation between the mayor and Watts discussing the release papers.

After showing the police commissioner the video of Mayor Abbey's conversation with Watts, Maddock proposes a pact with the police force. After ambushing a caravan of corrupt cops, they find no guns. KITT informs Michael there is another group of police cars headed for the local mall. Maddock convinces Daniels to allow KITT to pursue them.

When they arrive, Watts has begun a transaction with a gun buyer. When one of the corrupt cops guarding Watts sights Shawn moving in, he shoots her, and then the buyer and Watts flee. Michael catches up to Watts and disarms him. A fight ensues between Michael and Watts, Michael only stopping when Watts picks up his handgun. Shawn (only slightly wounded) arrives with the other handgun, instructing Watts to drop his. Michael talks Shawn down from shooting Watts. Watts then draws another gun hidden under his coat but Michael draws out an ultrasound gun and shoots Watts, who falls to his death.

After Watts' defeat, the mayor is incarcerated, Michael returns to retirement, and KITT remains behind at the Knight Foundation with Shawn and Maddock. The trio continue their police work.

Sarah and KITT track down Traceur, who turns out to be her childhood friend, and whom she was involved with has not seen since he left home at 18. They find him at the Montecito Casino, playing poker to repay his debt. He is resistant when Sarah asks for help, but agrees when she offers to pay his debt. The two set out to find out what happened to Graiman and discover who is after them.

Rivai arrives at Graiman's home and is asked by the local sheriff (Chris Mulkey) to identify the body. She discovers it is not Charles Graiman; the real Graiman (Davison) escaped through the woods and left a body double behind. Graiman makes his way to the home of Traceur's mother, Jennifer (Susan Gibney). The two leave for a local motel.

The men chasing them are mercenaries for Black River, a security contractor. They are after Prometheus, a system that controls the entire United States defense network. Information needed to control the system is contained on Graiman's hard drives in the mercenaries' possession, but is encrypted; only Graiman and Sarah know the encryption keys. KITT also possesses the data and can access the system.

Graiman contacts Sarah and asks her to meet him at the motel. He advises Sarah to contact Rivai for help. When she does so, Rivai puts her phone in speaker-mode so the sheriff can hear the location, unaware that the sheriff is working with the mercenaries.

KITT, Sarah, and Traceur find that the mercenaries have reached the motel, but have not found Graiman, as he checked into four different rooms. Using KITT's infrared sensors, Traceur finds Graiman with his mother and rescues them. Jennifer and Graiman reveal that Traceur's father was a man named Michael Knight and that he drove the first KITT, forcing him to stay away from his family.

As the group is leaving, the mercenaries find them. They shoot and kill Jennifer. Graiman is taken away and the other two are left to kill Traceur and Rivai as well as watch over Sarah and KITT. Just as they are about to be killed by the mercenaries, Traceur and Rivai overpower their capturers. Traceur and Sarah take KITT to chase after Graiman while Rivai stays with Jennifer's body.

Traceur and Sarah discover KITT's vulnerability to damage, due to the loss of his self-repair capabilities while his system is deactivated. After exchanging fire, Traceur reactivates KITT with just enough time to activate his armor without allowing the mercenaries to hack into him, and turns KITT directly into the mercenaries' path, causing a collision. KITT survives with no damage, while the mercenaries' SUV is heavily damaged. Graiman survives while his captors are mortally wounded or dead.

On the way to Jennifer's funeral, Graiman reveals that he's re-forming the Foundation of Law and Government (FLAG) and offers Traceur the chance to drive KITT. He refuses due to philosophical differences, saying "I just don't believe in the same things you do."

At the funeral, Traceur meets his father, Michael Knight (David Hasselhoff), who tells him what Wilton Knight once told him on his death-bed - that one man can make a difference - and that he (Knight) was that man. They shake hands and as Knight prepares to leave, Traceur asks if they will ever meet again. Knight responds back to his son, "I hope so."

Traceur is behind KITT's wheel in an enclosed area. Rivai, Graiman, Sarah, and Fass bid him farewell and inform him of his mission. Sarah kisses him goodbye and a door opens behind him that shows a moving road. KITT and Mike drive out in reverse. The door is the cargo hatch of a C-130 Hercules cargo plane which then takes off.
