Sole is a girl who loves life, though she only discovers as much when she meets two boys who are very different from her: Alex and Pierpaolo, who belong to the "Civil Disobedience", a group of graffiti writer named after Henry David Thoreau's essay. Sole joins them in their nocturnal adventures, filled with clashes, ideals and thrills, discovering her real identity and the value of friendship. But when she falls in love with Alex, the tensions she unwittingly sets off ultimately prove to be dangerous. "Write it on the Walls" is a story of love and friendship, but also a voyage through the world of today's young people, fuelled by adrenalin, fun and conflict.
