A man is forced to go against his family and his principles in the name of serving his country in this drama inspired by actual events. Tommy Santoro (James Marsden) was just a boy when his father was murdered, and young Tommy quickly discovered his dad was a high-ranking member of the Philadelphia Mafia. Tommy grew up determined to stay on the right side of the law, but his brother Vincent (Brad Renfro) and cousin Joey (Giovanni Ribisi) had other ideas and ended up joining "the family business." Tommy enlisted in the Army and served in Operation Desert Storm, but when he impulsively stole a jeep, he was arrested by the military police. However, Tommy finds he's not questioned by MP's, but by Horvath (Brian Dennehy), an FBI agent who knows all about his past and family history. Horvath has learned that Sicilian mobsters have been taking over the Philly rackets, and persuades Tommy to join up with Vincent and Joey in order to infiltrate the Mafia and serve as an informant to the FBI. Tommy grudgingly agrees, but he's uneasy about betraying his family and following the path that killed his father, especially when he discovers his actions have put Vincent and Joey in grave danger.
