La sociedad del semáforo (2010)

By applying all his knowledge in electricity and electronics, Raúl Tréllez, a bum who lives in the downtown streets of Bogotá, struggles to control the time of a red light so that jugglers, cripples and other homeless people can achieve longer shows in the red light corner.
