Synopsis:
Batman and Robin track down the Terrible Trio, who have recently escaped prison. The Vulture and the Shark are involved in smuggling operations which Batman shuts down, but the crooks escape.

Batman then disguises himself as convict Archie Craig. The Fox agrees to smuggle Craig past the police. When Batman reveals himself, the crooks are prepared and capture both him and Robin. Fortunately, Batwoman has trailed Craig and prevents the heroes from being launched into outer space. The three heroes then defeat the Terrible Trio.
