The Nameless (1999)

Synopsis
Spanish director Jaime Balaguero brings us this jet black horror thriller. Claudia (Emma Vilarasau) and Marc's beloved six-year old daughter Angela, dies under mysterious circumstances. Flash forward five years, and Marc has left while Claudia wiles away her time watching family videos of happier times. Angela suddenly inexplicably calls saying "They wanted you to believe I was dead." Claudia immediately calls an ex-cop, Massera (Karra Elejalde), to investigate the matter. To make matters worse, Claudia finds herself stalked by psychotic ex-boyfriend Toni, who simply radiates evil. As the movie progresses, Massera and Quiroga (Tristan Ulloa), a journalist who works for a magazine specializing in the occult, uncover a bizarre sadistic cult that sacrifices children. ~ Jonathan Crow, All Movie Guide
