François Truffaut had always made his love for Alfred Hitchcock clear, and his final film is a comedy thriller with a definite Hitchcockian undertone. A company boss is accused of murdering his wife and her lover, and the evidence seems to support this. Whilst he is hiding from the police, his secretary takes on the role of detective and uncovers illicit love affairs, prostitution rings and skeletons in everyone's closets before she uncovers the truth.
