Walker (Lee Marvin) strides through Los Angeles with the steel-eyed stare of a stone-cold killer, or perhaps a ghost. Betrayed by his wife and best friend, who gun him down point-blank and leave him for dead after a successful heist, Walker blasts his way up the criminal food chain in a quest for revenge. Walker kills without remorse, guided by shadowy "informant" Keenan Wynn, whose own agenda is carefully concealed, and assisted by Angie Dickinson, as he desperately searches for someone, anyone, who can just give him his money. But if Walker is an extreme incarnation of the revenge-driven noir antihero, the modern syndicate has been transformed into a world of paper jungles and corporate businessmen, an alienating concept to the two-fisted, gun-wielding gangster. Boorman creates a hard, austere look for the film and fragments the story with flashes of painful memory, grafting the New Wave onto old genres with confidence and style.
