Catch a train ride to danger.
Traveling from Beijing to Moscow, a missionary couple (Emily Mortimer and Woody Harrelson) quickly discover their trip will be a lot more nerve-wracking than originally planned.
There are heroin smugglers, compromised local cop Ben Kingsley — who dispenses violence as sharply as he trims his goatee — and multiple ways a person could not make it to the end of the line.
Director Brad Anderson keeps the suspense humming, while Mortimer is aces as a woman desperately trying to do the right thing after being unexpectedly thrown into the deep end of the swimming pool.
