Surrounded by the darkness of the past

Sara is a shy teenager who made a mistake a year earlier and thus lost her father's trust. She is framed for theft by her stepsister, as a result of which her father sends her to a correctional center. The first days in the new place are a real nightmare for the girl. She is bullied by her peers, and her lack of assertiveness makes Sara unable to cope with the surrounding environment. The roommate is a scrambler; however, she can always count on her help. There is also a new guy — Alan, who catches Sara's attention at the first meeting.
More problems arise when the girl miraculously avoids death, and since then, she begins to see frightening phenomena. Ghosts, flashes from the past are all dark secrets that come to light over time, and this is only the beginning of the nightmare the teenager will face.
