Frozen River (2008)

"Frozen River" is the story of Ray Eddy, an upstate New York trailer mom who is lured into the world of illegal immigrant smuggling when she meets a Mohawk girl who lives on a reservation that straddles the US-Canadian border. Broke after her husband takes off with the down payment for their new doublewide, Ray reluctantly teams up with Lila, a smuggler, and the two begin making runs across the frozen St. Lawrence River carrying illegal Chinese and Pakistani immigrants in the trunk of Ray's Dodge Spirit.
