An unusual look at the world of graffiti through the story of Sandro, aka Kenzo144. The step from illegal to legal graffiti and the damage estimated at 300,000 Swiss francs that weighs on his life. A journey through a culture hard to penetrate or define, concluding with the fulfillment of a dream: painting in the Bronx with some of the writers leaving their tags in New York City in the 1970s.
