Claude is a small and silent boy who carries around a box to which he keeps adding dials, antenna, etc. His parents are extremely rich, throughout the film Calude’s father keeps telling his son: “Claude, you’ll never amount to anything.” Mother several times exasperatedly asks him: “Can’t you do anything, Claude?”. Claude says nothing but, in the end, he has the last act: he twiddles the dials on his completed box and vaporizes both parents.
