Betty Boop tells her naughty nephew Junior a corrective fairy tale (with herself as fairy). Part of the action is replayed in reverse. Betty Boop tries to get Junior to bed, but he's being a bad little boy indeed. He unbuttons his sleeper, forcing Betty to re-button it. And after Betty turns off the ceiling lamp, Little Jimmy jumps up on his bed and turns it back on again. Once Betty thinks she finally has Junior to sleep, she finds him painting stripes on the cat with toothpaste. Junior begs Betty to tell him a story, and she does so with an eye toward teaching him a lesson. It's about a mischievous little boy, much like Junior, watched over by a fairy, who is much like Betty. He ties a tin can on a little dog's tail; he throws bricks at a glass house; and he clips off the shaving-brush-like hair of the local barber as he sleeps. But the boy goes too far when he taunts a lion, who escapes from his cage and chases him.
Betty Boop: "Now be a good boy and go to sleep."
Betty Boop: "Oh my...why aren't you asleep?"
Junior: "I don't wanna go to sleep!"
Betty Boop: "Now you must go to sleep!"
Betty Boop: "You go back to bed!"
Junior: "Aww, I wanna hear a story."
Betty Boop: "Alright sit on my lap and I'll tell you a story."
Junior: "I'm sorry, I'm sorry I didn't obey, please help this once and I'll do as you say."
Junior: "I don't believe a word you said it's not true but I'll be good and go to bed just for you."
Betty Boop: "That's a good little boy now run along."
