Fang Han makes his first appearance as a recalcitrant, smart police officer, while his girlfriend Luo Fei, who has gone undercover into a drug cartel, is murdered.
Fei Luo's body is recovered. Han Fang tries to call her from the training camp, but Fei Luo's phone is answered by Chudong Han instead. The police at the special forces training camp are sent on a new mission.
Fang Han begins to be suspected by Gu Tao but manages to maintain his trust. Drug dealer Qi Ke asks Gu Tao for help in delivering a consignment of drugs but is rebuffed. Jin Lanlan makes her first appearance as the proprietor of a bar.
Fang Han finds out about Luo Fei's relationship with Gu Tao. Jin Guihua, Jin Lanlan's godmother, hooks Gu Tai up to Ji Sanbao, a drug dealer. Qi Ke helps Mao Zi hide from Gu Tao.
Qi Ke orders his gang to assassinate Gu Tao's sidekicks. Fang Han is injured during the battle, which goads Gu Tao's sidekick Qi Xia into looking for Jin Guihua.
