When a retired East End villain is murdered by a feral street gang, his brother Ritchie Archer returns to London from Spain to investigate. With the police thwarted at every turn, Ritchie decides to take the law into his own hands and bring old school justice back to the streets of East London. Rounding up his old firm, he leads a vigilante crusade against the vicious young criminals, using every grisly method at his disposal to find and punish his brother's killers. A vicious street war follows, with no prisoners taken on either side, leading to a dramatic conclusion as the feral youths lay siege to a hospital Ritchie's firm is holed up in. They're outgunned and outnumbered, but this firm has never been outclassed yet.
