One year after the deadly events of last year's Halloween, Jess (Marina de Sousa) keeps having the same nightmare over and over where she finds herself helpless in front of a masked killer. Her friend Pierre (Vincent Conty) invites her to spend some time with him at his house and decides to throw a cosy and innocent pyjama party to try to keep her mind occupied. While her nightmares seem to be getting intense by the minute, Jess can't shake the idea that the killer may be back to pay her a visit.
