A man wakes up at the bottom of a cave, in a hostile environment, with two strangers and his faithful dog for sole company. He is chained by the wrist to a wall of the cave, one of the other men is chained by the ankle, and the third man is free but is wearing a horrific mask which will blow up should he walk away from the other two. Who brought them there, and why?

Soon another question will ask itself, more and more urgent: how far must they go to survive?

Frank Thilliez manipulate characters and reader in a chilling exploration of the human soul.
