Rio. Luiz, 14, kicks a ball against the wall. Left foot, right foot, it becomes a metronome. The rhythm escalates as we gather moments from his life. Racing friends up the Selarón Steps. Pickup games in Botafogo. Dancing samba with a pretty girl in Lapa. Move your feet: the rhythm is everywhere, on the field & off. It builds to a crescendo. He puts his jersey on & steps out into Maracanã ... Snap back to the moment: it’s just you, the ball, & the wall, left foot, right foot. Never Stand Still.
