Brad Anderson directs this tense, psychological thriller set on the Trans-Siberian railway, as an American couple become trapped in a deadly game between smugglers and the authorities. Deciding to travel back to Europe via the scenic route from Japan, American couple Roy (Woody Harrelson) and Jessie (Emily Mortimer) meet up with fellow travellers Carlos (Eduardo Noriega) and Abby (Kate Mara). Although outwardly friendly, Jessie's suspicions about the couple eventually rise to the surface, and when Roy returns to the train after being stranded, in the company of Russian narcotics cop Grinko (Ben Kingsley), her alarm bells start ringing. As the intrigue and tension build, with nothing seemingly what it appears, Roy and Jessie find themselves ensnared in murder and deception as they desperately try to escape their vacation from hell.
