The study of a particular category of horror movie, the slasher, draws us onto the stage of the adolescent experience, both in terms of its content and its form. The skeleton of the uncanny and its syncopated temporality offers one a glimpse of a common unconscious issue. The adolescent finds a solution for how to represent and elaborate the central issue of the feminine in the identifiable figures of killer and victim. The slasher movie as a vehicle for a degraded initiation rite is a resource for the adolescent facing the upheavals of puberty.
