A nerdy accountant (Ewan McGregor) is swept into a world of illicit sex and high-stakes intrigue by a charismatic stranger (Hugh Jackman). The film almost qualifies as a guilty pleasure—Hitchcock for Morons—until it completely derails in the final act. Just when there should be snappy “gotchas!” and satisfying confrontations, the film pauses for an unnecessary sex scene (yes, such things do exist) and lots of random images of flying birds. Anyone who has seen a suspense thriller before will figure out all the twists and turns, but it’s cheesy fun . . . for a while.
