Oscar^® winner Meryl Streep gives a powerhouse performance as Gail, a mother who organizes a white water rafting trip to celebrate her son's birthday and salvage her shaky marriage. A former river guide, Gail's no longer the risk-taker she was in her youth, but her skills and courage are put to the ultimate test when an encounter with three mysterious strangers threatens to turn a family vacation into a living hell.

Also starring Kevin Bacon and David Strathairn, this "pulse pounding thrill ride" (Rolling Stone Magazine) is a masterpiece of action, suspense and unforgettable storytelling from the director of "The Hand that Rocks the Cradle."
