Mosquito, Dragon, White Monkey and Dog Boy are members of the 'Gang of Princes' gang from the Monga area. Geta, one of the leaders of a gang from Monga who is also Dragon's father, teaches them the laws of the brotherhood and that they must always fight to protect their honor. The boys soon love their new gangster life and come up with a plan to become the biggest gang and take over the streets. Little do they know, however, that there are others who are jealous of Mosquito's successes. A gang from another area tries to put their name on the map by befriending Wen Qian, the leader of a rival gang, so they can take down the leaders of the gangs from Monga. Mosquito gets wind of this.
