Debut action-packed thriller about a strange girl who escaped from a sect and her life in a new family. Based on true events. Returning home from school, fifteen-year-old Jules Mathis finds a stranger there. The girl's mother works at the hospital and explains that May is one of her patients who will be staying with them for a couple of days. But soon Mae starts wearing Jules' clothes and sleeping in her bedroom, doing work for the school newspaper, and even kissing her boyfriend. Later, everything becomes even more confusing. Seeing the half-naked May, Jules is struck by the pentagram carved on the girl’s back. Some time later, white roses are found on the porch, one of Jules' sisters is bitten by a rabid dog, and her parents, who until that moment lived in peace, quarrel behind closed doors. Putting everything together, Jules finds out that May has probably escaped from a strange sect that has captured nearby town. And they will stop at nothing to get her back.
