Little Cheeser is a young mouse who thinks he's grown up. When Mama sends him to bed, calling him "Mama's little man," his devil side leads him to the pantry for cheese, then to smoking supplies, a racy magazine, and booze, while his angel side tries to stop him. Drunk, Cheeser goes looking for the cat, but the encounter quickly sobers him. Meanwhile, the angel traps the devil in a copy of Dante's Inferno and helps Cheeser escape. Grateful to be safe, Cheeser happily goes to bed as Mama's little man.
