Intro. (bl) Tobby is a twenty -year -old who lives alone in a huge old house who has inherited from her grandparents. His quiet life is as simple and boring as possible, until one day he realizes that strange things are happening in his house, as if someone else was sneaking, scouring his things and putting everything carefully in place again. Tobby discovers that he has a stalker, and that this stranger seems to be completely fissured by him, following each of his steps and seeming to know every detail about his life. The young man knows he should leave as soon as possible and call the police, but he has no money or anywhere else, and his stalker does not seem to want to hurt him, so Tobby decides to stay at the house until he can find a way out. But realizing that your shadow wants much more than just looking at him from afar, things start to get even more complicated for Tobias
