Omens and concepts of good vs. evil have no place in Maggie O’Connor’s (Kim Basinger) well-ordered, practical universe.
Her life revolves around her job as a nurse at a busy New York hospital — that is, until her wayward kid sister, Jenna (Angela Bettis), shows up on her doorstep one rainy Christmas Eve and saddles Maggie with an autistic newborn child named Cody (Holliston Coleman).
Cody quickly touches Maggie’s heart and becomes the daughter she has always longed for. But six years later Jenna suddenly re-enters her life and, with her mysterious new husband, Eric Stark (Rufus Sewell), abducts Cody. Despite the fact that Maggie has no legal rights to Cody, FBI agent John Travis (Jimmy Smits), an expert in ritual homicide and occult-related crime, takes up her cause when he realizes that Cody shares the same birth date as several other recently missing children.
The little girl, it soon becomes clear, is more than simply “special.” She manifests extraordinary powers that the forces of evil have waited centuries to control, and her abduction sparks a clash between the soldiers of good and evil that can only be resolved, in the end, by the strength of one small child and the love she inspires in those she touches.
