A mysterious beast stalks innocent children in this thriller from Spanish director Juan Carlos Fresnadillo. In the 1980s, Juan (Izan Corchero) is a young boy with an active imagination and a talent for writing stories. However, he is being terrorized by a strange creature that lurks in his room late at night and doesn't seem to have a face. Juan's mother Luisa (Pilar Lopez de Ayala) is skeptical at first, but comes to believe demonic forces are at work and asks a local priest (Daniel Bruehl) to chase the spirits out. However, it soon becomes obvious Satan is not the one to blame for the horrible visits. Three decades later, John (Clive Owen) and Susanna (Carice van Houten) are the parents of Mia (Ella Purnell), a 13-year-old girl. John is fiercely protective of his daughter, and when she's attacked in her room late one night, he's determined to find whoever or whatever is responsible. As it happens, Mia is being visited by Hollowface, a monster similar to the one who was stalking Juan, and he's just as difficult to frighten away. Juan Carlos Fresnadillo's first directorial project after his commercial breakthrough with 28 WEEKS LATER, INTRUDERS was an official selection at the 2011 Toronto International Film Festival.
