Synopsis by Hans J. Wollstein
The train carrying Dr. Graves destroys only Dave's parachute, the agent (Kirk Alyn) having landed safely alongside the tracks. Back at the National Museum, a person identifying himself as Dr. Graves is handed the missing Dr. Clayton's notes about the Golden Hands of Kurigal. But, as Dave discovers, "Dr. Graves" is actually Mack (Dale Van Sickel), one of Spade Gordon's many, many operatives. When Mack is killed in a car chase, Gordon (Roy Barcroft) and Nila (Carol Forman) worry about a certain key their associate had found in the late Dr. Williams' study. Said key, as Dave and Laura (Rosemary La Planche) discover, opens a safe located in a meat packing plant, but as Dave reappears with a package that may contain one of the missing statues, he is confronted by Gordon. During the ensuing struggle, yet another henchman (Tom Steele, this time sporting scar and mustache) takes off with both package and Laura. In hot pursuit, Dave can only watch in horror as Laura tumbles out of the getaway car right in his path.
