Li Luli witnessed his mother being killed by President Li in his childhood and was adopted by the Gu family in the south. Years later, he returns to the Li family feigning amnesia, also coming for revenge. The two reunite in the Li family, probing each other, only to discover that the other is their long-lost childhood sweetheart. Ruan Linfeng, the warlord's son, gets entangled in this grievance due to investigating a smuggling case. The three form an alliance, forcing Li Shenglong and Warlord Ruan Wentian to tear each other apart. In the end, Li Shenglong is executed, and the Haicheng opium smuggling is completely cleared.
