Goku and Krillin are training for a World Martial Arts Tournament to be held in the country of Mifan. The Emperor of Mifan, Chiaotzu, is trying to find his lost "Ran Ran." The minister, Master Shen, has Pilaf and his gang work on a Global Dragon Radar, takes it from him, and is using it to locate the Dragon Balls. Minister Master Shen and General Tao claim that they will use the wish from Shenron to locate Ran Ran, but are actually planning, with Tien Shinhan's help, to kill Chiaotzu and take over the country.
