Wife is jealous of tree shaped like a woman

A sheriff investigating the disappearance of a young girl from a small island discovers there's a larger mystery to solve among the island's secretive, neo-pagan community.

Police sergeant Neil Howie is called to an island village in search of a missing girl whom the locals claim never existed. Stranger still, however, are the rituals that take place there.

Is that a tree trunk in her mouth? What would the neighbors think? This is what mom does when she is alone.
