Lin Kai (Huang Xuan) is a police detective haunted by his tragic family past. He is assigned a secret – and potentially deadly mission: He must go undercover to infiltrate the notorious Twin Eagle drug cartel, which has taken a policeman hostage. The cartel’s mastermind is the ruthless Eagle (Duan Yi Hong), a man consumed with anger after an undercover policeman killed his wife a decade ago. Lin Kai’s mission is straightforward but highly perilous: Posing as a drug trafficker, he must win Eagle’s confidence and take the cartel down from the inside. But the seedy world of drugs and crime is full of temptation and potential pitfalls. Can Lin Kai keep his head above water and bring Eagle to justice – or will he get sucked under by the very monsters he came to destroy? “Extraordinary Mission” is a 2017 Chinese action movie that was directed by Alan Mak and Anthony Pun.
