The Orphanage(2007)

Laura spent the happiest years of her childhood growing up in an orphanage by the seaside, cared for by the staff and fellow orphans whom she loved as brothers and sisters. Now, thirty years later, she returns with her husband Carlos and Simon, their 7-year-old son, with a dream of restoring and reopening the long abandoned orphanage as a home for disabled children. The new home and mysterious surroundings awaken Simon's imagination and the boy starts to spin a web of fantastic tales and not-so-innocent games. As the opening day draws near, tension builds within the family. Carlos remains skeptical, believing that Simon is making everything up in a desperate bid for attention. But Laura slowly becomes convinced that something long-hidden and terrible is lurking in the old house, something waiting to emerge and inflict appalling damage on her family.
