An ancient evil has returned to continue the study it began over a century ago, and it's looking for volunteers. Isaac Winters is the perfect test subject. He's a detective with a damaged past, and something to prove. It moves like a virus from person to person, carefully selecting its next host, and leaving a trail of incinerated bodies in its wake. Accompanied by a partner short on experience, Isaac must uncover and defeat this faceless villain before it takes from him the greatest gift he's ever recieved. His daughter.
