Following a successful drug raid to steal US$10 million from the cartel’s money, John “Breacher” Wharton (Arnold Schwarzenegger) and his rugged team of undercover DEA task force — James “Monster” Murray (Sam Worthington) and wife Lizzy (Mireille Enos), Joe “Grinder” Phillips (Joe Manganiello), Julius “Sugar” Edmonds (Terrence Howard), Eddie “Neck” Jordan (Josh Holloway), Tom “Pyro” Roberts (Max Martini), and Bryce “Tripod” McNeely (Kevin Vance) — are happy to collect it later where they hide it in the sewer pipes. However, they return to discover that the drug money has gone missing. They are eventually held for investigation and everyone ends up suspended from duty. But after the authorities fail to land hard evidence against them, their superior (Martin Donovan) put them back into action. Then, one by one from Breacher’s team members ends up dead in gory fashion. While trying to find out the culprit, Breacher is subsequently working with homicide investigator Caroline Brentwood (Olivia Williams) and realizes that the murders as well as the stolen drug money is actually involving one of them.
