When Jake LaMotta steps into a boxing ring and obliterates his competitor, he is a prize fighter. However, if he treats his family members and friends the same wayhe's a time bomb, ready to set off at any given moment. Something always seems to come between them, though LaMotta wants his family's love. Perhaps it's his bouts of paranoia and jealousy. In real life he pops up at the ring alone, although this kind of rage helped make him a champ.
