If Lee Falk had anything to do with this serial I don't know.
Mandrake (Warren Hull) and Lothar (Al Kikume) help Professor Houston (and his lovely daughter Betty - Doris Weston) protect his radium energy machine from the head of an underworld gang, a sinister criminal genius known as "The Wasp".
The Wasp will stop at nothing to steal the scientists invention. His evil machinations to obtain the device include blowing up a radio station, a power plant, and a dam. Fortunately, his dastardly deeds cause only minimal damage because of the timely intervention of the quick-witted Mandrake, who has vowed to stop The Wasp.
Today one can find this serial on video's and dvd's
