A group of students with distorted faces stand in a dimly lit room with a clock on the wall, then a student descends a staircase holding a knife, followed by a close-up of a bloodied foot, a knife blade, a student with a bloodied back, and finally a student falling to the floor with blood splattered on the wall and floor.
