In a dystopian Detroit, abandoned brick mansions left from better times now house only the most dangerous criminals.
Unable to control the crime, the police constructed a colossal containment wall around this area to protect the rest of the city. For undercover cop Damien Collier every day is a battle against corruption. For Lino, every day is a fight to live an honest life.
Their paths never should have crossed, but when drug kingpin, Tremaine kidnaps Lino's girlfriend, Damien reluctantly accepts the help of the fearless ex-convict, and together they must stop a sinister plot to devastate the entire city.
