Dark City (1950)

Danny Haley’s bookie operation is shut down, so he and his pals need money; when Danny meets Arthur Winant, a sucker from out of town, he decoys him into a series of poker games where eventually Winant loses $5000 that isn’t his… then hangs himself. But it seems Winant had a shadowy, protective elder brother who believes in personal revenge.
