Charles Hodgson is a British aristocrat who decides to become a thief as a way of getting at his twin brother, Earl, a security expert who has built a supposedly impregnable vault in Tel Aviv, which holds a cache of diamonds. For the caper, Charles enlists Archie, a heist expert, and Sally. He also becomes acquainted with an American woman, Zelda Shapiro, who is in Israel looking for a new husband.

Lepke is the feared leader of "Murder Incorporated" in this underworld drama based on the life of Louis "Lepke" Buchalter. Lepke began his criminal career as a petty thief in his teens; a stretch in prison taught him the finer points of life on the wrong side of the law. After getting out of jail, Lepke and his pal Gurrah Shapiro join a gang who hire themselves out as strikebreakers, and the vicious but clever Lepke soon rises through the ranks.
