J. Dastardly Deeds, the evil genius, has figures out a way to use a cat's nine lives to create eight duplicates of himself. He tells his duplicates to committ crimes and he call Atom Ant to have tea with him.
Atom Ant comes over and as they are talking, the chief of police comes in and says that Dastardly robbed the bank. Atom Ant says that he couldn't since he was here with him the whole time. The chief then gets a phone call about Dastardly committing crimes around the country and the chief thinks he's made a mistake, but Atom Ant is suspicious.
Atom Ant tells Dastardly that he has to go and he leaves to watch Dastardly's house and see what is going on. He sees the duplicates come in and Atom takes action. Dastardly and his duplicates try to destroy Atom Ant but Atom comes out on top and Dastardly surrenders.
Later on, the Dastardly duplicates and Dastardly himself are now the prison baseball team.
