Synopsis: Filmed almost entirely on location, Walk a Crooked Mile was Columbia Pictures' "answer" to 20th Century-Fox's late-1940s cycle of documentary-style crime dramas. FBI agent Dan O'Hara (Dennis O'Keefe) and Scotland Yard operative Philip Grayson (Louis Hayward) team up to investigate a security leak at a Southern California atomic plant. Their investigation takes them to San Francisco, where a communist spy ring flourishes under the auspices of Igor Braun (Onslow Stevens). With such actors as Raymond Burr and Philip Van Zandt playing the commie agents, it's a wonder that the whole lot of them weren't arrested on sight before the story even began! Louise Allbritton plays the nominal female lead, a suspicious atomic scientist named Toni Neva.
