Девочка в подвале

After her mother suffered an aneurysm, 10-year-old Cameron was adopted by her Aunt Mia, who had a husband and a daughter. Soon after coming to her new home, Cameron started hearing strange, ghostly voices at night and realized that they were coming from behind the basement's locked door. She went on to discover that behind the door, people were chained to the wall--innocent victims of her aunt's scheme to enrich herself by cashing their benefit checks. Soon Cameron herself was demoted to the basement, where she would stay for the next 10 years while police thought she was missing. Based on real-life events.
