The Raft

Follow two pairs of strangers in a war between relentless beasts -- the sea and their own will to survive. They must last seven days at sea while battling the scorching tropical sun, high seas, ferocious storms, hunger, thirst, and man-eating predators. But survival isn't dependent on individual persistence and determination alone. There's one caveat--each person controls each other's fate. If one quits, the adventure is over for the both of them.
