In 2018, in a dystopian Detroit, abandoned brick mansions from better times house dangerous criminals. Unable to control the crime, city officials built a colossal containment wall that is 40 feet tall and has been constructed around this area known as the projects, or the "no go zone" to protect the rest of the city. Police monitor all movement in and out of Brick Mansions in which schools and hospitals in this dangerous area are shut down. For undercover cop Damien Collier (Paul Walker), every day is a battle against corruption after the death of his father. For French-Caribbean ex-convict Lino (David Belle), every day is a fight to live an honest life. (Lino starred in District B13 and continues his role in this story. ) Damien maintains a charming, intelligent, and consistent character throughout the film. Lino is hunted by drug kingpin Tremaine Alexander for stealing a massive amount of heroin and emptying it down a bathtub. Lino evades capture and so Tremaine has his men capture Lino's girlfriend. Lino attempts to free her and together they manage to escape and capture Tremaine in the Projects, turning him in to police at the boarder wall. Initially Lino was deceived by trusted police officials as he was under the assumption that Tremaine was wanted for being a highly dangerous criminal. Lino was not aware that Tremaine had been making payments to the police station as police officials were corrupt. Formerly trusted police officials allow Tremaine to leave with Lino's girlfriend and lock Lino up in a prison cell. Lino kills a police official in attempt to escape and save his girlfriend. Lino is put in the back of a police van where he meets Damien, an under cover cop playing the role of another prisoner.

At first, Damien and Lino fight both verbally and physically, but they quickly learn how to work together for the greater good as Damien reluctantly accepts Lino's help and together they struggle to save Lino's girlfriend and stop a sinister plot that involves a stolen bomb set to destroy the entire city. Moreover, there is also some girl fighting action between Lino's Spanish waitress girlfriend and Tremaine's assistant that portrays herself to be bisexual. To overcome Tremaine is not an easy task as he is an incredibly powerful leader with an army of heavily armed individuals ready to protect him at any cost. Eventually, with the help of Lino and Tremaine, Damien realizes at the end of the film that his father was killed by his fellow officers that he trusted and that the mayor of Detroit was behind the plot. Damien, Lino and Tremaine confront the mayor and manage to prove his true intentions and have him publicly humiliated on the news after compromising plotting an attack on Brick Mansions precedence and then he is arrested.
