The southern city of Miami has always been a breeding ground for drug crimes. The US Federal Bureau of Investigation (FBI) has never relaxed its surveillance of this area, especially the big drug lords who are well-known in Latin America, which have long been the focus of the police's most attention.
Due to a mistake in the work of the Joint International Team (JLATF), a very large drug trafficking gang slipped away under their noses, and the FBI immediately appealed to the Miami police for help. So Miami police sent a number of competent police detective involved in the investigation, in which tough guys Ricardo () and network specialist Trudie Yuepu Lin () consisting of a couple partner, through secret exploratory Go to the drug road in southern Florida, and be responsible for finding the real culprit behind drug smuggling-related murders. Colonia their peers Sonny Crockett () is a small drug dealers posing as undercover into a drug trafficking gang in southern Florida. In order to get close to the core of the group, the romantic and suave prodigal son Sonny frequently dated Isabella (Gong Li), an Asian Cuban woman, but he did not expect to be self-defeating. The two actually fell in love with each other. Sonny is so deeply involved in the emotional entanglement with Isabella that he can't help himself. He walks on the edge of danger between black and white, and finally has to make a painful choice.
The Asian woman is the first leader behind the drug smuggling group, and the wife of Montoya (Luis Dosa), a famous drug lord and arms dealer. This unavoidable reality has brought unprecedented trouble and danger to the investigation of the entire case. When Ricardo finally made progress in the undercover investigation, he found that the other party was suspicious of them, so, in order not to reveal his identity, he sent someone to kidnap his girlfriend Trudy. At this time, Ricardo, the police and various law enforcement agencies were forced to take immediate action, hoping to rescue Trudy who was taken hostage in time, and at the same time arrest the suspect who planned the drug trade in one fell swoop.
The situation is getting more and more serious. Ricardo and Sonny, who are between the two hostile parties, are becoming more and more confused about their undercover identities. They have to walk on the edge of the law when performing undercover operations, and sometimes have to violate them. Believe in the principles of law enforcement. Their hearts are constantly struggling.
