Hold Back the Dawn begins with a shabby immigrant (Charles Boyer) wandering onto a Paramount sound stage and telling his life story to director Mitchell Leisen (who actually directed this film). In flashback, we see that Boyer was once a conscienceless gigolo, desperate to flee Nazi-occupied Europe. He makes it to Mexico, where he pretends to fall in love with shy schoolteacher Olivia de Havilland. It is his plan to marry her, thus be able to enter the United States; then he intends to dump her and pursue the woman he really loves. Boyer's regeneration, and the price he pays for his previous callousness, brings Hold Back the Dawn to its tearful conclusion.
