When a fellow ranger (Julian Madison) is brutally murdered, the Captain sends Dave Austin to investigate the crime, only to stumble upon a money-laundering scheme in the works. With one eye on the killer (Ted Adams), Austin tries to unravel the racket. But keeping his true identity under wraps could be a problem. Rex Lease and Marion Weldon co-star in this classic Western from prolific director Sam Newfield.
