A hood named Dugan is on his way to a rendezvous with his gang and their leader, Colonel Kincaid. But while en route, he is ambushed and captured by Michael, who assumes his identity and reports for duty in his place. With the help of a girl named Linda, who is being blackmailed into staying with the gang, Michael determines that Kincaid is planning to break open a federal penitentiary and sends K.I.T.T. ahead to advise Devon. But at the last minute, Kincaid pulls a switch, and the job is changed; instead they are going to rob a truck bearing a supply of gold bullion. It's too late to advise Devon of the change, so Michael and Linda are forced to go along with the gang for better or worse. But with their ingenuity and K.I.T.T.'s assistance, they subvert the robbery, capture the gang, and deliver them to the penitentiary.
