Over a period of three years, elusive artist Peter Gibson, a.k.a. Roadsworth, made his mark on Montreal by launching a self-described "attack on the streets." Armed with spray-paint, handmade stencils, and a boundless imagination, he began to paint life into the concrete, overlaying urban asphalt with bold imagery. A crosswalk became a giant boot print, traffic dividers transformed into zippers, electrical plugs filled parking spots. While many appreciated Roadsworth's unique creations, others denounced the work as pure vandalism, an act of "artistic anarchy" to be punished by law. With tremendous tenacity and vision, director Alan Kohl paints a portrait of a man struggling to defend his work and define himself as an artist while confronting larger questions about the nature of art and freedom of expression. What emerges is an adventurous and powerfully inspiring film that asks the question: "who owns public space?"
