Law and Order (1953)

Wild West lawman Frame Johnson (Ronald Reagan) arrests a notorious outlaw, but, after the locals threaten to break into the prison and hang the crook without a trial, Frame gets fed up with injustice. He decides to put his days of gunslinging behind him in favor of a simple domestic life with his lover, Jeannie (Dorothy Malone). The couple move to the supposedly idyllic Cottonwood -- only to find that their new home has been overrun by a rogue rancher who has unfinished business with Frame.
