Eight years after taking down Fouchet,
Miami PD detectives Mike Lowrey and Marcus Burnett are investigating drug trafficking of
MDMA in
Miami. They infiltrate a
Ku Klux Klan meeting, only to discover that they are buyers, not distributors. After a radio malfunction leads to a delayed arrival of the Miami Police's Tactical Narcotics Team (
TNT), Mike and Marcus end up in a shootout with the Klansmen. While covering Marcus, Mike inadvertently shoots him in the buttocks. These antics reinforce Marcus's doubt about whether he should stay partners with Mike, who is secretly dating Syd, Marcus's younger sister. Marcus waits to tell Mike he's transferring out of the TNT Unit. Unbeknownst to both, Syd works undercover for the
DEA as a money launderer for the
Russian mafia branch in Miami, who are acting as middleman distributors via their nightclubs for drug lord Hector Juan Carlos "Johnny" Tapia. After laundering the money, Syd is intercepted by a
Haitian American Zoe Pound gang while transporting it. Mike and Marcus, following an informant's tip, engage in a massive gun battle and car chase through Miami and the
MacArthur Causeway, causing major damage. Captain Howard reprimands them and is upset that the DEA is investigating the city without his knowledge. Mike and Marcus track down the Haitians, interrogate the leader, and learn from a video that Tapia uses a local
mortuary as a front. They pose as pest exterminators at Tapia's Miami home for more intel. Meanwhile, Tapia strong-arms the Russian Mafia boss Alexei into signing over ownership of all the Florida nightclubs owned by the
Russian mafia by dismembering his lieutenant Josef and threatening Alexei's family, thereby giving Tapia uncontested control of the Miami illegal drug trade. Mike and Marcus stumble upon the remains of Josef during their search and take a severed finger for an ID. Impressed with Syd's work, Tapia starts a mixed business-personal relationship with her, planning for her to launder all his money. Later, Mike and Marcus infiltrate Tapia's mortuary. Inside, they discover that Tapia is using cadavers and coffins to smuggle drugs and money in and out of the country. The evidence is sufficient for Captain Howard to authorize a raid on both Tapia's residence and the mortuary, in collaboration with the DEA and the
U.S. Coast Guard. Almost all of Tapia's drug supply and money are confiscated in the raid. Tapia flees to
Cuba with Syd as a hostage after learning she is a DEA agent during the raid on his home. He demands his money back in 48 hours, using Syd as a bargaining chip. Mike and Marcus form a black-ops team with the DEA, TNT, and Howard's contacts from the
CIA to rescue Syd. They are inserted by the Coast Guard off Cuba, where they meet Tito, Vargas's brother, who leads the local
Alpha 66 resistance. Tito helps with weapons, tunnels, and mapping Tapia's mansion. The team raids Tapia's mansion, rescues Syd, and leaves a large explosive device that demolishes the mansion upon the team's exfiltration. Marcus, Mike, Syd and Tito steal a yellow
Hummer H2 as they escape from Cuban military forces controlled by Tapia. Tapia survives and pursues the group, ultimately ending up outside of
Guantanamo Bay. Not recognized as U.S. citizens, the
Navy personnel on the base shoot at both Mike and Marcus as well as Tapia's vehicles, prompting them to stop just as they enter a live minefield. Marcus kills Tapia while the latter holds Mike at gunpoint. Tapia's body falls backward onto a mine, which obliterates his corpse. Mike, Marcus, and Syd celebrate at a barbecue in Marcus's backyard with his family; Marcus has decided to remain partners with Mike. ==Cast==
