Big Boss (1975)

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.
