Lethal Hostage

As the drug trafficking raged on the Sino-Burmese border, an anti-drug officer accidentally uncovers a major drug trade through a cold-blooded assassin. The trade involves the head of a Yunnan criminal gang named 350, who wants to go into retirement with his young wife Xiao An afterwards. In flashbacks, we learn that Xiao An was actually kidnapped by 350 as hostage, but slowly develops Stockholm syndrome and voluntarily lives with him in Burma. (rotten tomatoes)
