Twenty years ago, "Tazhai Village" in Thunder's anti-drug campaign was wiped out in one fell swoop. However, the young and ruthless Lin Xiao, a direct disciple of the core drug-making master "Lin Yaodong", managed to escape with the most critical "Perfect Ice Crystal" formula and some funds and sneaked into the Golden Triangle. Twenty years later, a new drug trafficking group "Xin Tazhai" with "Remnants of Tazhai" as its technical core, integrating local warlords and international capital, quietly emerged, and penetrated into the country through secret channels a new type of extremely pure and extremely harmful drug "Phantom".
Lei Zhan, leader of a certain detachment of the border armed police (the nephew or adopted son of the second uncle, who inherited the legacy of the second uncle), discovered the connection between the "Phantom" and the Tazhai technology of that year during an arrest operation. He realized that the poisonous snake that slipped through the net twenty years ago had now grown into an evil dragon entrenched outside the country. An ultimate showdown spanning two generations of border police, involving undercover agents, gun battles, intelligence and counter-intelligence, begins here.
