In Jerry Lewis's first film in a decade, he plays Bo Hooper, an unemployed circus clown who can't seem to hold down a job. The film opens with a brief montage of clips from past Lewis movies. He then moves into a succession of jobs that he gets himself fired from including a gas station attendant and a mailman - all with disastrous results.
