Reaching for a curiously shaped stone in a southern California riverbed, Kurt, a motherless 13-year-old out on a father-son bonding camp trip, feels a pulsing tremor of energy. Confused, he shares this oddly colored rock with his two friends, both who touch it briefly and throw it away in cries of pain. Unsure what to do, the three boys agree to keep this strange phenomenon a secret.

After bringing the stone back home, he senses he’s being followed, possibly by a lone detective. To add to his unease, the city of San Diego is besieged by what seems like a disturbing and violent serial killer, one who leaves distinctive clues, as if he (or it) is itching to get caught.

When he finally makes contact with Steve Bailey, an unflinching detective with a disturbing past, Kurt uncovers his own startling heritage of power, danger and, ultimately, justice.

In this unnerving urban thriller, the creators have reunited with their demons, and humans with inherited, but unwieldy gifts, may be the only barrier between survival and celestial destruction.
