Synopsis:
A small nuclear device has been stolen and is being used to blackmail Gotham City. Batman enlists the aid of gangster Big Brill to identify the blackmailer, but first he must survive several death traps set up by Brill and his men. Working against the blackmailer's deadline, Batman follows clues until he finds the bomb inside the trunk of a parked car. However, a remote triggering device could still activate the bomb.

Gotham officials agree to pay the blackmail demands. Batman follows the money to the blackmailer, Bertram Smith. The man is killed at the airport, but not before he reveals that the remote trigger is hidden inside a young boy's ball. Batman finds the boy and the ball in time to deactivate the trigger and save Gotham.
