In a London neighborhood plunged into chaos and violence, an old-school war veteran lives a solitary and routine life. Harry, an elderly man who has lost his wife, feels trapped in a world where crime and hopelessness are everyday protagonists. His only companion is his friend, who has also seen better days, but life in the neighborhood is becoming increasingly dangerous, especially after the death of a young man who falls victim to the brutality plaguing their streets.
After witnessing the growing danger threatening his community and dealing with the ineffectiveness of the authorities, Harry decides it’s time to take action. Armed solely with his determination and a couple of old memories from his military training, he embarks on a personal crusade to eradicate the evil that has taken hold of his home. However, his path to justice will not be easy; he will have to confront a small gang of young delinquents who will stop at nothing to maintain their control.
As his quest for revenge intensifies, a game of cat and mouse ensues, where Harry becomes an unexpected hero. This brutal and moving journey not only tests him physically but also raises profound questions about morality, justice, and the cost of vengeance.
