The Narrow Margin | Full Movie | Movies Anywhere

On a train bound from Chicago to Los Angeles, hard-boiled detective Walter Brown must protect the widow of a gangster who's slated to testify before a grand jury. Brown's (Charles McCraw) partner was murdered while guarding the ill-tempered Mrs. Neall (Marie Windsor), and the friction between the detective and his charge grows in the confined space. Now, the mob will stop at nothing to kill Mrs. Neall before they reach Los Angeles, and every passenger on the train could be an assassin--or a potential victim. But Brown does not know who he can trust, even the woman he is risking his life to protect, in this film noir classic.
