Scene of the Crime

When assigned to investigate the murder of a fellow plainclothes policeman, Los Angeles cop Mike Conovan (Van Johnson) follows his hunches straight to a burlesque dancer named Lili (Gloria DeHaven). With a tip from Lili, Conovan trails and arrests a mysterious man spotted at the scene of the crime. After the suspect is gunned down, Conovan's wife (Arlene Dahl) convinces her husband to quit the force -- but can the detective stay away from the case after another fellow officer is murdered?
