每年夏末，新泽西市郊的一群孩子们都会参加Camp Hope。他们回来到森林深处，拜托城市的纷扰。在这里，他们在神父的领导下学习如何分辨善与恶。然而，神父却不小心带来了一件邪恶的东西，将这个原本安全的地方变成了地域。。。

At the end of every summer, the children of a Christian community from a suburb of New Jersey attend Camp Hope. They travel deep into the woods far from any distractions the world provides. Here, the children are taught the ways of the Lord, the perils of the flesh, and the horror of the Devil. A charismatic priest leads them in their training. But, he unknowingly has brought something with him, something evil. What was supposed to be a safe place, a spiritual retreat has now turned into a nightmare that not even faith can end.
