One by one, the physical, emotional, psychological and sexual obstacle course of life in the camp forces the guests to confront their own demons. One by one, the doors to their troubled pasts are opened and for each guest, an intense emotional rollercoaster begins. But Bart has dark unresolved secrets of his own. And when the group learns that their guru is not the hero they hoped for, when the true facts about his past and his lies come to light, the roles are reversed.
