A sleuth in touch with the spirit realm investigates an evangelist cult leader in this paranormal historical mystery.

San Francisco, 1917. The city is bustling with change and restless ghosts. Blessed (or cursed) with the ability to peer into the other side, Delia Martin once used her gift to defeat a twisted serial killer. Now as her beloved city is on the threshold of a modern age, Delia lives a peaceful life with Police Captain Gabe Ryan.

That peace shatters when a strange young girl starts haunting their lives. While attempting to discover what this ghost wants, Delia becomes entangled in the mystery surrounding a charismatic preacher who advocates an end to war. But as young people begin to disappear, and his followers display an increasingly fanatical fervor, that message of peace reveals a hidden dark side.
