Three soldiers take an unexpected cross-country trip to Las Vegas. A handsome know-it-all (Michael Pena) seeking the confidence to face his wife, a middle-aged father (Tim Robbins) planning to hit the casinos in a desperate last-ditch effort to pay for his son’s college tuition, and a beautiful young woman (Rachel McAdams) longing to reunite with her boyfriend’s family make the long journey together, as three very different Americans find their way home.
