Six schoolboys between 16 and 18 are waiting in their classroom for their new teacher. Every teacher who was supposed to teach this class up to now has given up.

One of the boys is keeping a lookout. As soon as they hear footsteps they barricade the door with their desks. But nobody comes. They decide to play teacher themselves while they are waiting. Each boy takes a "lesson" and the others interrupt. During these "lessons" the boys talk about themselves, their troubles, their hate, their fear and their longings. When they discover that the teachers have given them up, a bloody conflict develops. No more teachers are going to come. After an outburst of aggression during which the classroom is destroyed, things break down - with the door still open they wait for a teacher, but school is over.
