George Clooney, Mark Wahlberg, Spike Jonze and Ice Cube are Gulf War soldiers who find a treasure map on a captured Iraqi soldier.

So they decide to go and get the loot, leading to a mesmerising mixture of black comedy, violence and off-the-wall film-making.

The most persistnet problems facing the four on their surreal journey are a cow, bullet wounds, kidnapping and troublesome mobile phones but, throughout, the action never lets up and the wisecracks flow freely against a background of startling imagery.
