Knight Rider

Knight Rider (the HOFF) -- a shadowy flight into the dangerous world of a man who does not exist. Michael Knight, a young loner on a crusade to champion the cause of the innocent, the powerless, the helpless in a world of criminals who operate above the law. Michael Knight, a lone crusader in a dangerous world. The world... of the Knight Rider.
Knight Rider's shadowy flight was broadcast on NBC. It was a spin-off of Diff'rent Strokes.
