But when he is sent to the U.S. to buy weapons, Frankie is housed with the family of Tom O'Meara, a New York cop who knows nothing about Frankie's real identity. Their surprising friendship, and Tom's growing suspicions, forces Frankie to choose between the promise of peace or a lifetime of murder.
