Buster is a stagehand who doses off backstage, where he dreams he is every member present at a symphony including the band members, conductor, and the audience members. He awakens to engage in vaudevillian zaniness which includes impersonating a missing monkey and rescuing his sweetheart when her water submersion trick goes wrong. This early Buster Keaton short is whimsical and funny, again showing the wide range of the master's talents.
