Two brothers face their personal demons in this crime melodrama. Donald Martin (Van Johnson) is an alcoholic criminal who has escaped from prison and needs help crossing the Mexican border to freedom. Desperate, he arrives at the ranch of his lawyer brother Martin (Joseph Cotten). Martin has little respect for his brother and would prefer his neighbors not know he's housing a fugitive, so he tries to convince people that Donald is actually someone else. Donald is crushed by his brother's shame and rejection, and, after a drinking binge, he decides that he should try to make the journey into Mexico on his own. Martin's wife Nora (Ruth Roman), who has her own issues with Martin, convinces him to put his differences aside and help Donald however he can.
