Orphan

One of my favorite movies is the story of terror "Orphan." The movie portrays Esther, a girl of nine years who lives in an orphanage, where a couple adopts. The problem is she hasn’t 9 but 33 years, she has a disease called type Nanimos and Leena and was hospitalized in a mental institution in Estonia. She gets out and gets fire to her adoptive family (before going to the orphanage). Esther kills several characters in the movie only surviving mother and daughter.
I advise you to see the movie, especially people who like horror stories.
