In this comic version of a classic story, a very human and stagestruck cow, Drusilla, wouldn't mind being sold by the poverty stricken Jack if her new owner would place her in a show. Youngsters in the audience take part in the play as the actors draw them in and encourage them to express their opinions about the story and characters. The plot follows the story of Jack selling Drusilla for a bag of beans. His mother throws them out the window, where they shoot to the sky and the giant's castle. In Jack's escape from the Giant, Drusilla saves the day by coming back in time to chew the vine down and destroy the Giant.
