Alpha Dog (2006)

1999, Claremont, California. Middle-class 20somethings talk trash, wave guns, hang out in a pack. Johnny Truelove, drug dealer and son of a underworld figure, threatens Jake Mazursky, an explosive head case who owes Johnny money; Jake responds by breaking into Johnny's house. On impulse, Johnny and a couple of pals kidnap Jake's 15-year-old brother Zach. Zach's OK with it, figuring that his brother will pay the debt soon. Johnny assigns his buddy Frankie to be Zach's minder, and they develop a brotherly friendship. Zach parties with his captors as things begin to spin out of control. Group think, amorality, and fear of prison assert a hold on the pack. Is Zach in danger?
