During World War II, an American serviceman in London decides to impress his English girlfriend by acting as an American gangster, which soon turns deadly.

In World War II London, Karl Hulten is an American serviceman and Betty Jones is an aspiring showgirl. When they meet, passion and desire fuel a dangerous fantasy: he is the big-time gangster named Chicago Joe; she is his glamorous moll. They go for a reckless drive, they steal a fur coat, each time she dares him to take a wilder risk, and each time he proves himself. Until their lust for excitement demands nothing short of going "all the way" - to murder. This is the shocking true story of two strangers who meet, mingle and lack into a dangerous world of their own.—Artisan Entertainment
