Djan, William, Ricardo and Biscoito live in the favelas in Sao Paulo. They are four young men with a drive and inspired vision to make a difference. Simple Graffiti doesn't adequately describe what they do, as their mission is more politically entrenched. They climb the highest buildings, at huge personal risk, in the most unlikely places to paint their slogans and messages. Often called anarchists or criminals, they prefer to call themselves soldiers. When invited to Berlin, in recognition of their artistic work, no one can suspect what they are about to do. Their belief in pushing the boundaries, of defying laws or standards, can only end up landing them in hot water. For all their adventure, their recognition and good intentions, there is, ultimately, a price to pay.
