Synopsis:
Batman crashes the Batplane in a remote mountain area. Crooks learn of the crash from a weak radio signal. They decide to raid Gotham while Batman is out of action. To help them, they recruit Harry Larson, an ex-con and Bruce Wayne look-a-like, to play Batman.

Larson is struck in the head while taking on a rival gang. Robin finds him and believes him to be the real Batman. Larson's injury causes partial amnesia, so he too thinks he is Batman.

Batman eventually makes his way off the mountain, but the crooks find him. They believe he is Harry Larson and has double-crossed them. They leave him in a death-trap to die.

Robin eventually realizes Harry is not the real Batman. When he sees Batman in the death-trap, he believes it to be an imposter. Harry recovers his real memory and saves Batman, but he is killed by a high voltage charge. Batman proves his identity to Robin and helps capture the crooks.
