The Sea Chase

Captain Karl Ehrlich (John Wayne) is the master of the aging German steam freighter Ergenstrasse, home port Hamburg, docked at Sydney, Australia, on the eve of the Second World War. Ehrlich is a former German Navy officer who lost his command after refusing to support the Nazi regime. As his ship prepares for sea to avoid internment, Erlich meets with an old friend, British Royal Navy Commander Jeff Napier (David Farrar), plus Napier's German fiancée Elsa Keller (Lana Turner). Ehrlich knows Elsa has a dubious past and tries to break them up by reminding Elsa of her past trysts, to which she chuckles and smiles.
