According to a company press release, the film tells the story "of two brothers on opposite sides of the law. When one brother is murdered, the other, a retired police detective, finds himself pulled back into the criminal world he left behind to solve the mystery surrounding his younger brother’s death. The film climbs to a violent conclusion, fueled by passion, family loyalty and revenge." In addition to Sirico, who plays retired detective Tony Zarra, the film also stars Brendan Fehr (Roswell, CSI: Miami) as Tony’s nephew, Gaetano, and Erin Cummings (Spartacus: Blood & Sand). Academy Award-nominated Renee Taylor (Life During War Time, Love and Other Strangers), Wass Stevens (The Wrestler), Kathrine Narducci, Kelli Barrett, Brian Tarantina, Michael Badalucco (The Practice, Boardwalk Empire) and Academy Award-nominated Burt Young (Chinatown, Rocky) round out the cast.
