The king of special forces, Chen Mo, retired from the army due to the sacrifice of his comrades, and went undercover alone in the Golden Triangle drug cartel. Next to the drug lord Kun Sa, he dealt with the fatal temptations of power, money and beauty. After experiencing betrayal and life and death tests, he always adhered to his original intention. He and his liaison officer Lin Yuwei secretly fell in love and supported each other in desperate situations. In the end, Chen Mo collected irrefutable evidence and joined forces with the international police to launch "Operation Thunder" to completely destroy the drug trafficking empire. He completed the memorial service at the tomb of his comrades, and walked hand in hand with Lin Yuwei towards a new life, spending the rest of his life lighting up the light of drug control.
