Revolver (2005)

The year is 2010. Teenager Alan Tracy, sent off to a distant boarding school, is the youngest of the sons of Jeff Tracy, a retired American astronaut. Jeff, a widower, has formed International Rescue, and raised his sons to act as a secret, volunteer organization which uses highly advanced technology to save lives worldwide. Jeff and his older sons John, Virgil, Scott, and Gordon, who like Alan were named after the Mercury Seven astronauts are joined in this effort by Lady Penelope and her butler/chauffeur Parker. Their futuristic hardware is largely developed by a genius scientist known as Brains, who lives at the International Rescue base on Tracy Island, somewhere in the Pacific.
After seven years in solitary, Jake Green is released from prison. 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?
