In the next two years, he amasses a lot of money by gambling. He's ready to seek his revenge on Dorothy (Mr. D) Macha, a violence-prone casino owner who sent Jake to prison. He humiliates Macha in front of Macha's lieutenants, leaves, and keels over. Doctors tell him he has a rare disease and will die in three days; Macha also puts a hit out on him. Loan sharks, Zack and Avi, demand Jake's cash and complete fealty in return for protection. Jake complies, and through narration and flashbacks, we watch him through at least three days of schemes, danger, and redemption. Who is his greatest enemy?
