The Abbott and Costello style pairing of Brown and Carney has them cast as radio detectives on the hunt for murderous criminologist Atwill, known as "The Cobra." This was smoothie villain Atwill's final film before his sudden death and marked the end of the Brown-Carney duo. Lugosi fulfilled his three-picture deal with RKO by taking the mindless role of Stone, the Cobra's right-hand man. Modestly funny at times, but mostly not. A remake of the 1937 SUPER SLEUTH.
