Out of a job and with his marriage on the rocks, a former boxer (Vince Vaughn) begins working as a drug courier to provide for his wife (Jennifer Carpenter). His fortunes improve, until a drug run gone wrong and a vicious gunfight land him behind bars, where he is forced to commit increasingly brutal acts of violence to survive the prison battleground and protect the ones he loves. "Brawl in Cell Block 99" is written and directed by S. Craig Zahler, the acclaimed writer/director behind "Bone Tomahawk."
