Catman escapes jail again with the intention of stealing a statue of the Egyptian cat goddess Bast.
Two man are locked up in the same cell, one known as Collins and the other Blake, who is Cat-Man. After a time of self induced catanoia, Blake wagers with Collins over defeating Batman and winning Collins hidden loot, or having to hand over the Cat-Man suit.
What ensues is a cat and bat game through Gotham museum. Robin (Jason Todd) is neturalized and less then effective in helping. With Batman disoriented with the sounds of the Cat-Man, he fights for his life.
In the end, there is more then one Cat, and the Batman costum is worse for wear.
