A critically injured woman arrives in the emergency room. She has been hit by a car and left naked and brutalised.

When Special Agent Will Trent visits the scene of the incident, he stumbles on a torture chamber buried beneath the earth. It's clear that this woman is not the only victim of a sick, sadistic killer. Wrestling the case away from the local police chief, Will and his partner Faith Mitchell soon find themselves at the centre of a grisly murder hunt.

Haunted by their own wounds and secrets, will Will and Faith have what it takes to stand between a madman and his next crime?
