Malevolence (2004)

Antonio owes the Robaldo family a hundred G's, Gray wants revenge on the street gang who mugged him, Jimmy's escaped from prison, and his brother/accomplice David has many serious mental conditions. Detective Brickley is hot on their trail willing to stop them with any means necessary, while a pair of rogue psychiatrists track them to discover the roots of David's condition. It isn't long before the paths of these characters cross with violent and tragic consequences. The result is a shocking and disturbing portrait of human nature at its worst that can only be summed up in one word: Malevolence.
