Michael Long, an undercover police officer, is shot while investigating a case and left for dead by his assailants. He is rescued by Wilton Knight, a wealthy, dying millionaire and inventor who arranges life-saving surgery, including a new face and a new identity: Michael Knight. Michael is then given a special computerized and indestructible car called the Knight Industries Two Thousand (K.I.T.T.) and a mission: apprehend criminals who are beyond the reach of the law.
