Drama inspired by actual events. Tommy Santoro (James Marsden) was just a boy when his father, a high-ranking member of the Philadelphia mafia, was murdered. 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 Tommy ended up joining 'the family business'. Tommy enlists in the Army and serves in Operation Desert Storm, but when he impulsively steals a jeep, he is arrested by the military police. However, Tommy finds he's not questioned by MPs, 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.
