Confessions of a Pit fighter is a character driven action film about regret, consequences and the triumph of the human spirit. Eddie Castillo is a quiet man. He has survived seven years of incarceration in the state pen and wants nothing more than to live out his life in relative tranquility. He moves in with you younger brother David who as a kid, idolized him. Castillo soon learns that the "tranquility" he was seeking is shattered by David getting involved in illegal underground fights, the same type of fights that coincidentally led Castillo to Prison.
