An ancient stone amulet and calendar disc has the power to stop time. Passed from generation to generation, these magical artifacts end up in the hands of an 18-year-old half Shoshoni Indian named Justin, who chooses to to use his power to make the world a better place. But on the other side of the equation is the power-seeking philanthropist, Micahel Romano, who seeks to indulge in the riches of the world.

Clay, an eighteen-year-old freshman, comes back from his first term at a college in New Hampshire to spend his Christmas vacation with his broken-up wealthy family in Los Angeles. His former girlfriend, Blair, is now involved with his ex-best-friend, Julian. She warns Clay that Julian needs help: he is using a lot of cocaine and has huge debts. What follows is a look at the youth culture of wealthy post adolescents in Beverly Hills with a strong anti-drug message. Apart from the setting and the names, the film has very little to do with Bret Easton Ellis's book by the same title on which it was based.
