The Great Sinner

When accomplished novelist Fedja (Gregory Peck) becomes enamored of the stunningly beautiful and mysterious Pauline (Ava Gardner) on a train to Paris, he abandons his plans and instead goes with her to a German casino. Fascinated by the people he meets there and wanting to remain near Pauline, he decides to study the gamblers as research for his next book. Pauline, however, is a consummate gambler herself, and her addiction slowly pulls Fedja into a world of corruption and lost luck.
