El Internado is a Spanish show produced by Antena 3 that is based on a group of around 5 teenagers at a boarding school that is secluded out in the forest. The group encounters paranormal activity, missing students, and weird hiding places that all eventually end up leading back to Nazis and the war. The show also has many sub-plots including student-teacher relationship, and family turmoil, since the school also houses young children. While the show is currently not on Netflix anymore, it will most likely be back on within this year.
