Alpha Dog (2007)

When a young drug dealer by the name of Johnny Truelove kidnaps Zack Mazursky, the 15-year-old brother of a man in debt to him, things don't go according to plan. As he desperately tries to get the money owed to him, Johnny's crew looks after Zack. Though a hostage, Zack is enjoying the excitement of his situation, blissfully unaware of the fatal conclusion that awaits him. Inspired by a true story, "Alpha Dog" is a moving and tragic drama centred on the three fateful days when the lives of a few suburban kids were turned upside down forever.
