It is a comic retelling of the "Jack and the Beanstalk" fairy tale, produced by Abbott and Costello and distributed by Warner Bros. Eloise Larkin and her fiancé Arthur's plans to attend the rehearsal of a play are jeopardized because no one will babysit her obnoxious kid brother Donald.

Jack flirts with Cosman employee Polly, but he is thwarted by the arrival of her boyfriend, a towering police officer.

In his dream, Jack learns that a giant who lives in a castle in the sky and has taken all of the kingdom's food as well as the crown jewels.

His mother sends him to sell the last family possession, their beloved cow Henry, to the local butcher, Mr. Dinklepuss.

He comes to regret this decision when Jack mixes gunpowder with the chicken feed, causing the Giant's omelette to explode in his face.

They befriend his housekeeper Polly, who helps them escape over the castle wall along with the royal prisoners, Nellie and some of the giant's stolen gems (pilfered by the greedy Dinklepuss).

During the descent, Dinklepuss loses Nellie (who falls into the arms of Jack's mother) and then the gems, which rain down upon the impoverished townsfolk below.
