Professor Popov [named Gassonis, and Pissinger, in other language versions] invented a micro vibrator able to eliminate all forms of hate. The scientist inserts the prototype of his machine in his niece and assistant Eva - a young intersex woman - who must go through a number of situations to test the equipment. At one point, a local gangster abducts Eva to appropriate the machine, but he is really in cahoots with Popov - Eva and her friend Ajita,a black dancer, manages to fight the robbers and preserve the invention.
