In 1960, Bilal arrived for the first time at the Gare de l'Est in Paris. He was then 10 years old, did not speak a word of French but is already talented in the drawing. Years later, millions of albums sold around the world led to his success and popularity. Then he took another step in developing his post-apocalyptic worlds on the brink of explosion, inspiring his own films such as "Bunker Palace Hôtel", "Tykho Moon" or "Immortel (ad vitam)". This TV documentary (broadcasted on January 2010, France 5) shows how his graphic world and imagination are grown up around great poets (Baudelaire) or fantastic writers (Edgar Allan Poe, Lovecraft). And it goes beyond the image, to make us discover the wounded, deracinated artist still in the footsteps ("empreintes" in French) of his childhood.
