Asylums and Satanic Ritual Planning

3 teens and 4 kids go camping in a haunted forest that is 666 years old. Of course they have their parents with them (two children and one teenager belonged to an aunt and an uncle). They already know that 666 is the number of the beast and it is believed that many people in that forest did satanic rituals. Even more than once, there has been a forest fire. But will these people be able to survive in a Hell-like forest for 3 months?
