In a studio constructed in a barn, Mickey Mouse and his friends, Minnie Mouse, Horace Horsecollar and Clarabelle Cow, perform music for a radio broadcast. The listeners are all animals in the barnyard. The program goes smoothly, until a cat enters the barn and disrupts the music with his yowling. Mickey chases the cat out of the barn, but it returns through a hole in the door, followed by four unruly kittens. Mickey's attempts to get rid of the felines lead to the destruction of the instruments and the radio station.
In a contemporary review, Motion Picture Herald said: "It is all delightful, nonsensical and amusing."[4]
In Mickey's Movies: The Theatrical Films of Mickey Mouse, Gijs Grob writes: "The studio uses the cats to a great effect in a second attempt, after Mickey Steps Out, to build a finale from a string of gags. The film is not entirely successful in this, and only gains momentum when Mickey picks up the broom."[2]
