Strangers awake in a room, all locked by steel chains. Nobody remembers how they were captured, who brought them here. They find a sign on the wall saying: 'Memento Mori' and a safe with a timer in the middle of the room. Talking to each other to find any clues, they figure out that everyone in the room is hiding the sins they must confess to escape.
