Dani and Tommy discover that the vicious killings in East Salem were merely the birth pangs of a greater evil about to be born.

Occultist leaders at Saint Adrian’s school are in league with an East Salem pharmaceutical company. Together they’ve developed a drug that acts as a time-bomb in children, attacking and killing the prefrontal cortex—the moral center of the brain—once adolescence begins.

East Salem residents Dani Harris, forensic psychiatrist, and Tommy Gunderson, former pro-football player, have discovered the plan to deliver this drug into the water system and will stop at nothing to halt it. Their secret weapon? Reese Stratton, a student who barely escaped from St. Adrian’s—without his twin brother.

Now demonic creatures are terrorizing East Salem under the cover of darkness. Having killed two residents, the beasts have surrounded Tommy’s hillside home. But their deadly attacks seem to have been just a prelude to greater disaster: during a physical battle between angels and demons, a dam breaks, flooding the town of East Salem, but also washing it clean.
