Six French students, planning to play a joke to their P.E teacher, find themselves accidentally locked in the gymnasium. Unable to get out or to call anyone, they start to panic. Suddenly, the lights go off and strange noises can be heard. They are not alone.
Directed by Olivier Lallart and the students of the 4e D of the Collège Jacques-Yves Cousteau (France)
