This film tells the story of two friends, Jack and Jock, with their principle: "life is a series of games and challenges". The challenge is pretending to be a barber and to cut Alex’ hair (Alex is played by Darto Helm, who was a famous, bald comedian). Jack "plays" with the wife of Alex while Jock is “cutting” his hair. Jack, who gets a crush on Merry, succeeds to get acquainted with Merry through her aunt, by posing as a neurologist since Merry has a psychiatric disorder. Meanwhile, Jock gets acquainted with Lucy, a hotel maid.
