She is excited to make new friends, explore different cultures and, most importantly, start fresh in a place where nobody knows who she is and what she has done. When she arrives at the camp, however, Phoebe quickly learns of its violent, haunted history. As children begin going missing and she continues seeing things that aren't there, she unravels the truth about the camp's past.
