Mistress of the World Collection

Professor Johansson has made a huge scientific breakthrough; a device that will create a huge magnetic pulse that knocks out all electricity over a continent-wide area. The military applications are already being thought of when Dr. Johansson is kidnapped by a group of profit-seeking mercenaries. Meanwhile, his daughter, Karin, finds herself having to consort with all manner of shady characters as she searches for her father.

Karin is now continuing her father's research and is also caught in the cross hairs of the mysterious opponents. Johanson himself retreats to a Cambodian monastery in order to escape the gangsters' shots and recover. Meanwhile, the international criminals manage to steal Johanson's energy formula. Karin then goes after the thieves, supported by Lundstrom. But he also has his own goals. The hunt takes them around the world. It soon turns out that a certain Madame Latour is behind the sinister machinations. Eventually old Johanson falls into her hands. In Southeast Asia, a showdown ensues between the kidnappers and Lundstrom and Karin.
