Wu Min Chan and Kuang La Lung are subordinates of Commander of Northern Province, gunning for the post of Garrison Commander. On Wu's side are Shi Wen, and Sha Chung, while Kuang was assisted by Pei Chiang, Si Ma, and Niu Chung. Soon Shi gained power and sent Niu to kill Wu with Lui Yan's dagger, causing Lui Yan to commit suicide before the Commander. Niu became possessed with self-reproach, and was jailed for being drunk. Shi sent Pai Siow Lan, Niu's sweetheart to poison Niu. Pai drank the poisoned drink, and begged Niu to escape. Realizing Shi's true character, Niu went to seek Shi. In the end, Niu committed suicide after killing Shi.
