Gangs of New York

A territorial battle of hand-to-hand combat between William "Bill the Butcher" Cutting's U.S.-born nativist gang, the Natives, and "Priest" Vallon's Irish Catholic immigrant gang, the Dead Rabbits, concludes when Cutting kills Vallon, witnessed by Vallon's young son, Amsterdam. Amsterdam seizes the knife used to kill his father, races off, and buries it along with a medal his father gave him. He is later raised at Hellgate orphanage.
