Big Sponge is a young man living in a small town in China’s west who long ago broke out of the education system, left his parents, and struck out on his own. He wanders the streets, aimlessly getting through one long night after another. Big Sponge loves rap music and has a lot of musical talent, but his daily reality doesn’t allow him to put it to any use. He can only freestyle on the street, using music to deal with life’s joys and disappointments. Later, he took part in a robbery and was taken to trial. The pressure from the court case and the difficulties of his day-to-day life made it impossible for him to bear his current life any longer. In order to give himself more opportunities, he began to make some changes.
