Dong Chang, a gang boss who ruled the old streets for twenty years, has always believed in settling things with his fists, until his enemies chase him into a river. When he opens his eyes, he’s Zhang Qiang, a sixteen-year-old high school student who has just been in a car accident. Fresh out of the hospital, he gets beaten up by some elementary school kids on the street... The former boss clutches his scuffed school uniform pants and watches students with backpacks fool around in the distance, utterly bewildered for the first time: How can life at sixteen be harder than a turf war with his enemies?
