Set in 1930s Chicago, Jackie stars as Jerry Kwan, the son of a struggling grocer who has been feeling the squeeze from the local mob to pay “protection” money.  Although Jerry’s first inclination is to fight back, his father disapproves of these tactics, so the pressure only continues.  During a scuffle with some mob henchmen, Jerry catches the eye of the mob boss, Domenici (Jose Ferrer), who has a plan to win the “last man standing” brawl that means so much to him (and his betting prowess), by recruiting Jerry to his side with his amazing fighting technique.
