Boys' School

Three friends at a French boarding college form a secret society with one aim, to get to America. After a meeting one night, one of the boys sees a man step out of a wall. Christian-Jaque follows what happens next: the boy who spoke of it vanishes, then another, and when the drawing teacher Lemel (Michel Simon) turns up murdered, the last of the three has to find out what is going on before he is next.
