Babylon AD (2008)

A mercenary is hired to deliver a "package" - an innocent young woman raised in a monastery - from the ravages of a post-apocalyptic landscape of Eastern Europe to a destination in the teeming megalopolis of New York City. But this is hardly a typical job for the hardened gun-for-hire. As he, the young woman, and her fearsome guardian make the 6000-mile trek, they are threatened by a religious sect that has taken a special interest in the woman - who may hold the secret to mankind's salvation.
