Eight students. A lonely bridge on a dark night. When their school bus careens off the bridge and crashes into the river, they are lucky just to survive. But soon, they discover they possess strange powers, like the power to read minds, to fly, or to resurrect the dead. And that's just the beginning. None of them knows exactly what happened, and each remembers something different. Now, they are being hunted down one by one, and to survive they must piece together their memories and solve the mystery of the missing time.
