Frozen River (2008) - Melissa Leo, Misty Upham, Charlie McDermott

The story of Ray Eddy, an upstate New York trailer mother 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 on their new trailer, Ray reluctantly teams up with Lila, 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.
