The story centres around Linda Donner, a Boston native, who travels north to rural Nova Scotia and takes a post as a policewoman with the Royal Canadian Mounted Police in hopes of finding peace and balance in her life. Instead of a slower pace, things heat up as she becomes preoccupied with a controversial pastor she suspects is guilty of arson, murder and child abuse. She breaks into a church and finds the suspected pastor exorcising demons from a child. She believes she has caught him in the abuse act, but suddenly finds her own self powerless as she spirals into what appears to be a nervous breakdown. As she realizes she is fighting supernatural forces, she decides she must find God's help-a God she had stopped believing in after a priest seduced her when she was a teenager. The only person who seems able to help is her chief suspect, the pastor.
