This sequel to the films, Green Street and Green Street 2: Stand Your Ground about the rough and gritty world of UK football hooliganism, departs from the street corner brawls of the previous films and delves into the realm of organized fighting. Danny Harvey (Scott Adkins) is on a mission to find the killer of his younger brother who died in a pre-arranged football gang fight. He returns to London seeking revenge and discovers that his old gang, the Green Street Elite, is woefully out of shape and overweight. Knowing that the only way to find his brother's killers and exact his revenge, is for his gang to become the most feared fighters in London; so Danny vows to train the Green Street Elite in the art of mixed martial arts.
