Single mother Kate Reese and her son Christopher flee an abusive relationship, seeking refuge in the isolated town of Mill Grove, Pennsylvania. But when Christopher vanishes for six days, he returns changed—hearing a voice that demands he build a treehouse in the woods by Christmas, or his mother and the whole town will never be the same. Christopher's imaginary friend has a sinister mission, and the family must confront their darkest fears to save themselves.
