At a boarding school, three boys -- Serge Grave, Marcel Mouloudji, and Jean Claudio -- have formed a secret society with the skeleton in the science class room. Their purpose is to go to America, where they can be free. After a meeting, Claudio sees Robert Le Vignan appear suddenly, then disappear as suddenly. The next day, modern language teacher Erich von Stroheim -- who is always being teased into a rage by art teacher Michel Simon -- announces they will be studying H. G. Wells' THE INVISIBLE MAN. Claudio insists on talking about the man who keeps appearing and disappearing, so von Stroheim sends him to the headmaster, Aimé Clariond. Clariond remonstrates with him, and Claudio leaves.... and disappears. Grave and Mouloudji think he has gone to America, particularly when Grave receives a postcard from New York from Claudio, which von Stroheim steals. Then Mouloudji disappears. Simon gets drunk and when the lights cut out, tumbles to his death. Then Grave disappears. Where have they gone? And where did Simon get the money to purchase half a dozen original Durers?
Christian-Jaque is not considered a great director, but his work was always solid, and commercially successful. Here, working with a script partly derived from a Victor Hugo play, he offers a tale of three imaginative boys at a second-rate school, where the teachers know they've reached a dead end. He gives Simon a fine, unlikable role, and von Stroheim a chance to play with his usual screen image in an unlikely way, as well as a finale that echoes ZERO DE CONDUITE in a very amusing manner.
Charles Aznavour plays one of the students in his second screen appearance. I didn't recognize him as a 13-year-old boy.
