When Anna's daughter Joey goes missing, it's assumed to be the result of bad parenting - but dark forces are suspected when every child in town also disappears. The children return but show signs of demonic possession, and proceed to attack the town. Forced to wage a violent campaign against the children, the townspeople go on a bloody rampage, but Anna refuses to believe her daughter is lost to the devil and will do whatever it takes to save her from the demon inside.
