Radar Secret Service is a 1950 action film starring John Howard, produced by Barney A. Sarecky and directed by Sam Newfield.

In the post-World War Two era, Michael, a big wheel in the organized crime world, and his head man Mickey Moran, come up with a plan to steal a shipment of Uranium-238.

Radar Patrol decides to use a helicopter to see if they can detect where the rest of the material is hidden while Michael, Mickey, and a woman pretending to be a girlfriend to both of them, all try to come up with another plan.

During the show's fifth season, they were offered the rights but chose the movie only because "a piece of junk like Radar Secret Service was, in fact, the cream of the crop of the ... films" they had to choose from.
