I have watched this movie once, which was on .
A man awakens in a mangled car-wreck at the bottom of a steep cliff. Injured and trapped inside, with no memory of how he got there or who he is, he must rely on his most primal instincts to survive. But as he attempts to free himself from the carnage and escape an impossible situation, a darker side is revealed. Even if he manages to survive, the man may have to face the horrible consequences of an earlier, forgotten life.
