In the film, Mickey and the gang are throwing a party for all of their friends. Minnie and Clarabelle perform a song while Mickey, Horace, and Goofy (known at this time as Dippy Dawg) are in the kitchen preparing some refreshments. Once the refreshments are finished and distributed, an energetic jam session breaks out that causes the guests and even inanimate objects to dance to the music. As the cartoon ends, police officers arrive to seemingly put an end to the party, but end up joining it instead.
