US Fish and Wildlife Service agent Cory Lambert (Renner) discovers a body in the
rugged wilderness of the Wind River Indian Reservation. The FBI sends in rookie
agent Jane Banner (Olsen), but she is unprepared for the difficulties created by the
oppressive weather and isolation of the Wyoming winter. When she employs Cory
as a tracker, the two venture deep into a world ravaged by violence and the
elements.
