Horror staring Blythe Metz as Ellen Morris who, after receiving an African fertility mask, believes she is being pursued by something dark and sinister. When she tells her husband (Luciano Szafir) he convinces her to see a psychotherapist who diagnoses her as paranoid schizophrenic and recommends she be institutionalised. However, on their way to the clinic they encounter car trouble. While her husband goes for help, Ellen is attacked by an unknown aggressor and flees into a nearby forest, coming across a house where two couples are spending the weekend. They take her in after hearing her horrifying tale but as, one by one, the occupants are killed, those remaining start to question whether the danger is outside or in the house with them.
