From a torturous cell in Africa, Abel Powell is released and given the chance to regroup his team of skilled mercenaries for one last job. A top scientist will guide them half a mile underground through an ex-Soviet bunker to extract the vital specimens and information being paid for by a mysterious backer, but what they seek should never have been found!

Trying to recover from the nearly marriage-breaking stress following the death of their child, Jack and Stephanie spontaneously take off on a road trip. But when their car breaks down in a remote area, they find themselves in a horrific nightmare. Seeking shelter in a house, they soon realize that more danger lurks inside than outside in this spine-chiller based on Ted Dekker and Frank Peretti's best-seller.
