Two passionately dedicated San Francisco cops chase two insanely dedicated professional killers in Don Siegel’s gritty 1958 study in pathological relativism. The film moves in a pattern of tension and release, culminating in a brilliantly executed car chase over an unfinished freeway. A major B-movie by one of Hollywood’s most accomplished craftsmen, it stars Warner Anderson, Emile Meyer, Eli Wallach, and Richard Jaeckel.
