Disgraced detective Tony fakes evidence in divorce cases, implicates wife in Stasio affair. Stasio and wife shot dead in hotel. Tony's ex-partner Frank investigates, suspects inheritance-seeking mistress Angeline and inconsistent Tony.

Brighton, England, 1959. Disgraced cop turned private detective Tony Aaron falsifies adulteries for use as evidence in divorce cases. He involves his wife as the fictional co-respondent for painter Carlo Stasio but the pair are shot dead in a hotel room. In charge of the case is Frank, Tony's ex-partner still on the Brighton force. His most likely suspects are Angeline, Stasio's mistress who is set to inherit his house and pictures, and Tony himself, parts of whose story don't seem to add up.—Jeremy Perkins {J-26}

In the late 1950s, British police officer Tony Aaron (Neeson) resigns from the force after sleeping with Hazel (O'Neill), wife of the man whose house he was supposed to guard. In his new job as a fake private investigator, he helps couples get divorces by photographing Hazel having "affairs" with the husband. When she is murdered during a job, Tony begins having an affair with the dead man's mistress, Angeline (San Giacomo), while trying to prove his innocence.
