Jack lives the high life and wants to make Marjorie his one and only. He then learns that his deceased father is alive–but dying of lead poisoning. His father had sent him away 20 years before, to keep him out of the rackets. But now that he is dying, he wants to split the business between Giacomo (Jack) and Frank, his other son. The business includes running booze down from Canada. More on Wikipedia
