Deliverance (2013)

A young man wakes up in a morgue. He is naked, he doesn't know how he got there, but, most importantly, he does not remember who he is. He keeps on getting unconnected flashes, that don't build up a full picture, and his life in the real world resembles a nightmare - a prison that is impossible to escape from. But is this prison real or is it but a figment of his imagination?
