The Stranger is often considered Orson Welles' most "traditional" Hollywood-style directorial effort. Welles plays a college professor named Charles Rankin, who lives in a pastoral Connecticut town with his lovely wife Mary (Loretta Young). One afternoon, an extremely nervous German gentleman named Meineke (Konstantin Shayne) arrives in town. Professor Rankin seems disturbed--but not unduly so--by Meineke's presence. He invites the stranger for a walk in the woods, and as they journey farther and farther away from the center of town, we learn that kindly professor Rankin is actually notorious Nazi war criminal Franz Kindler. Conscience-stricken by his own genocidal wartime activities, Meineke has come to town to beg his ex-superior Kindler to give himself up. The professor responds by brutally murdering his old associate. If Kindler believes himself safe--and he has every reason to do so, since no one in town, especially Mary, has any inkling of his previous life--he will change his mind in a hurry when mild-mannered war crimes commissioner Wilson (Edward G. Robinson) pays a visit, posing as an antiques dealer.
