Cruising along the main arteries of the world's foremost urban centres, including Barcelona, Vienna and Marrakech, two French documentarians encounter the artists who have taken to the street and made it their playground, soapbox, and creative space. Discover with them how these visionaries are transforming the urban domain with a humanist style that's alive, but also untamed and anything but ordinary.
