When a young detective is ambushed in a failed police stakeout, he is believed to have been killed. In reality, he survives and learns that his face has been altered and his identity has been changed to Michael Knight. The man responsible for this is Wilton Knight, a dying billionaire who, convinced that one man can make a difference, has selected Michael for the role as a crime-fighter. (Parts 1 & 2 as one episode on Blu Ray)
Michael and K.I.T.T. head to the quiet backwater town of White Rock for Michael to take a well deserved vacation and do a little rock climbing, but the trip isn't quite the quiet break expected, when they find that the town is being terrorised by a rowdy motorcycle gang preparing to do battle with a rival club of bikers...
Michael and K.I.T.T. are about to test K.I.T.T.'s new function which should allow him to drive on water, but the test is aborted when K.I.T.T. detects an injured scuba-diver washed up on the shore. Befriending the young man's sister, Michael investigates just how the boy got wounded, and uncovers that he has been removing ancient Aztec treasure from a sunken galleon, falling foul of a determined treasure hunter...
Michael and K.I.T.T.'s latest assignment, to guard a volatile new isotope in Chicago, looks as if it could be their last, when the late Wilton Knight's daughter Jennifer plans to shut down their division of FLAG, and suspends Michael. But meanwhile, international terrorist Phillip Nordstrom kidnaps Devon, and uses hi-tech laser surgery on a criminal to create an impostor, as part of Nordstrom's plot to get his hands on the valuable isotope. Even though suspended, Michael becomes suspicious of (the impostor) Devon's behaviour and investigates — but Nordstrom plans to get rid of their interference, coating K.I.T.T. in a chemical to break down his molecular amour coating, before turning loose "The Juggernaut" — a deadly mobile battering ram...

Michael and K.I.T.T. must stop the gang before they use the computers to disrupt the test-run of a new computerised vehicle that is armed with a warhead...
When a Foundation trustee is murdered, Michael's prime suspects master magician Austin Templeton — but the man was seemingly on stage performing at the time of the murder. Michael is determined to prove that Templeton used his "magical" trickery to fool the audience and give him the perfect alibi. The fact that Bonnie, an old flame of Templeton's, was in the audience and is insistent of his innocence, does not make the case any easier...
Michael and K.I.T.T. have the seemingly easy, relaxing job of patrolling a national park for a couple of days, when they find themselves up against an arsonist driving an All-Terrain Vehicle, who escapes over rough terrain that K.I.T.T. can't cover. As they investigate to find just who is behind the spate of arson attacks, Michael must prove the innocence of a teenage boy, a reformed vandal, who is being framed for starting the fires...
