Ex-homicide detective Frank Langer's life is a mess. A year ago, after a mental breakdown, he was placed on extended medical leave from the squad he was once hand-picked to lead. A broken man, he spends his days drinking and chain-smoking, and his nights waking up screaming from a horrific recurring nightmare. Everything changes when a child goes missing and Frank comes to believe that the disappearance is part of a conspiracy.
When he shows up at the squad with his story, his former colleagues pat him on the back and tell him to go home. Undaunted, he convinces Rebecca Hanon, the aunt of the missing child, to join in his investigation. She agrees, provided Frank will allow her to help him confront the horrific event that led to his breakdown.
He delves deeper, struggling to connect the pieces of a deadly puzzle: a mute quadriplegic secreted away in a psychiatric hospital, a former research scientist hiding on a remote island, a dead reporter's ravings about a bloodthirsty cult commanded by a reclusive billionaire. The answer is more dangerous than he ever imagined, and telling Rebecca would put her life in danger. Soon even she comes to question his sanity.
Frank realizes that he has uncovered a conspiracy that threatens the entire human race. But can he find someone to buy his story before it's too late?
