On July 22, 1934, Roy Dillinger (identical twin brother of infamous bank robber John Dillinger) is warned by John's friend George that his brother has been set up by the FBI, who plan to arrest him while he is out on a date with Anna Sage at the Biograph Theater. Rushing to warn John, Roy is mistaken for his brother by an FBI agent who guns him down. John slips out during the commotion and realizes that his brother is dead.
Having grown weary of his criminal lifestyle, John returns home and decides to bury his past. He moves to the countryside, marries Abigail Dalton, and takes her surname as his own. They have a son, and John quietly takes up work as a farmer.
Several years later, in 1940, disgraced Chicago Outfit boss Al Capone is released from prison on medical grounds after being diagnosed with terminal neurosyphilis. His family moves him to a mansion in Florida, but Capone retains enough of his mind to realize that he is now effectively bankrupt, under heavy police surveillance, and abandoned by his former organization. Learning that the famous John Dillinger is still alive, Capone blackmails him to carry out one final heist: a vault, hidden by Capone in Chicago during his criminal reign, that contains millions in untraceable diamonds.
An Entertainment Weekly review in 1995 gave the film a "C minus" rating and described it as "far-fetched fiction".[6] Critic Leonard Maltin awarded the film two stars, and stated that the film is "boosted by slick acting, but it soon slides into a routine heist thriller."[12]
