Convicted (1938)

Police Detective Burns (Charles Quigley) is helping Jerry Wheeler (Rita Hayworth), a night-club singer, track down the killer of a gold-digger, for which crime her brother, "Chick," (Edgar Edwards) has been sentenced to die in the electric chair. She finds evidence that convinces her that Milton Militis (Marc Lawrence), owner of a nightclub, is the killer. She gets a job in the club as a singer in order to gain Milton's confidence and find the proof of her brother's innocence. Milton finally figures out she is spying on him, so he and a henchman take her for a ride and, with glee, planing on killing her at the same time her brother is being executed.
