Two slain officers lie in pools of blood on the street. There's no pattern to the killings and police are confused and scared. Only after gunshots splatter his partner across a back alley and Detective Lon McQ himself narrowly escapes death does the bloody rampage make sense. Now McQ knows whom to go after. John Wayne thunderously enforces the law in a high-velocity thriller that's like a big-city revenge Western on wheels. Directed by action master John Sturges ("The Magnificent Seven", "The Great Escape"), it careens around Seattle with the same eye for detail that the "Dirty Harry" series cast on San Francisco. Eddie Albert, Diana Muldaur and Colleen Dewhurst co-star in this breathlessly paced, gritty showcase for the Duke.
