Guadalupe has finished filming a horror film directed by MatÑas, an arrogant director who, along with his producer, wants success at all costs. When he invites the cast and crew to see the first cut of the film at his house, strange things happen: images that had not been filmed start appearing, and one by one, the people begin to die. Guadalupe, the "final girl" in the movie, must now save herself and his colleagues before it's too late.
