Family of Cops (1995)

"A one man cop shop in a two-timing town"

Paul Fein is a veteran police detective whose son Eddie is also a cop. Paul is assigned to investigate the murder of a prominent businessman, and he soon learns that the field of suspects has been narrowed down to two—the victim's sexually freewheeling wife Anna, and Paul's wild-child daughter Jackie. Neither Paul nor Eddie believe that Jackie could have committed the murder, and soon Paul is using himself as a decoy in a bid to find out more about what Anna does and doesn't know about her husband's death.
