The Great Plane Robbery. 1940
Special agent Mike Henderson (Jack Holt) has been assigned by an insurance company to protect gangster Joe Colson (Noel Madison). Joe has recently been released from prison, just three months before his life insurance policy, worth half a million dollars, is due to expire.
After Mike arrives at Leavenworth, Kansas on the day of Colson's release, he discovers that two gangsters, Eddie (Paul Fix) and Nick (Harry Cording), are there as well waiting to see Joe. They greet him and then board him on to an airplane. A following Mike also boards the plane. That night, Eddie and Nick storm the cockpit, and force the pilot to land near a lodge where Frankie Toller (Stanley Fields), Joe's successor, awaits. When they arrive, Frankie divulges that he will hold Joe prisoner until Joe reveals the location where his fortune is located. Later, he sees Mike and inducts him into the gang, believing he is one of Joe's old friends.
The airplane's disappearance becomes a worldwide sensation, and the next morning, the gang discovers that an insurance company detective had been a passenger on the missing plane. The gang assumes the person must be salesman Homer Pringle (Hobart Cavanaugh). Mike, managing to convince Frankie that Joe is completely broke, proposes that they force Homer to call the insurance company, with an offer to ransom Joe. Accordingly, Mike and two others go into town, where a fake killing of Homer is staged by Mike shooting him with blanks. Mike and the gang members return to Frankie, while Homer telephones the police. As Frankie prepares to flee, the police arrive, arresting him and the rest of the gang. Afterward, the plane is started again and the passengers finally reach their destination. Meanwhile, Joe is taken into custody for a different offense, assuring Mike that he will live out his policy.
