Security guard Sam White’s life falls apart when he arrives home to find his house a smoking ruin with the bodies of his wife and daughter inside. Then he receives a phone call from a stranger who claims that his wife and child are alive and Sam can still save them.
But first, he must complete a few simple tasks. Sam joins forces with Zack Parker whose life has also been ripped apart by the same sadistic foe, and together they plunge into the dark, labyrinthine underworld of Portland, Oregon. It’s a race against time to discover the identity of the kidnapper and save their families before it’s too late.
