This animated short about men and hair tells the story of little bald Léon and of his grandfather, an old man with a bushy black beard. A thing of legend, the grandfather's beard seems endowed with magic powers. It even turns caterpillars into butterflies! But Léon's grandmother wants to cut off the unkempt beard and regain the distinguished-looking man she married, who wore just a tidy mustache. When the old man's asleep, grandmother prowls, scissors in hand, but Léon's keeping a watchful eye on her. As long as grandpa lives, the beard will stay.
