 When a young detective is ambushed in a failed police stake out, he is believed to have been killed. In reality, he revives and learns that his face has been altered and his identity has been changed to Micheal Knight. The person responsible for this is Wilton Knight, a dying billionare who, convinced that one man can make a difference, has selected Micheal for the role as a crime-fighter. Now armed with a advanced car called KITT which has the equivalent armor of a battle tank, capable of speeds over 300 MPH and contains an artificial intelligence computer personality as an aide, Micheal agrees to perform his assigned role.
