On the Mekong River, the merchant ship "Warburg Pincus" was poisoned by the Golden Triangle drug lord "Black Scorpion" Sang Kun. Thirteen Chinese crew members were killed and slandered for drug trafficking. In order to clear the deceased's innocence and destroy the drug trafficking network, the Ministry of Public Security established the "Hunting Owl Action Team", led by the anti-drug hero Lu Feng, and jointly with intelligence expert Su Qing, sharpshooter Zhao Lei, and veteran boatman Ada, a family member of the deceased crew member, to pursue the cross-border pursuit.
The action team went through many hardships and used undercover clues to lock the drug traffickers' transportation line. Lu Feng was injured in the ambush at Ghost River. With the help of intercepted transaction ledgers, they uncovered evidence of Black Scorpion's collusion with border officials and locked down its core drug manufacturing factory disguised as a rubber plantation. On a rainy night, the police from China, Laos, Myanmar, and Thailand jointly launched a general attack. Zhao Lei sacrificed his life to protect his teammates. Lu Feng led his team into the factory, confronted Sang Kun on the tarmac, and finally subdued him.
Three months later, merchant ships on the Mekong River resumed sailing, with the five-star red flag fluttering in the wind. Lu Feng held Zhao Lei's commemorative blank bomb in his hand, witnessing that the river protected by the lives of drug police officers and innocent crew members regained its former peace, and the crimes were finally punished by justice.
