The episode opens on a peaceful farm when a space pod crashes down onto Earth into a farmer's marijuana patch. Piccolo is interrupted by the alien, who confused him for someone named "Kakarot." At Kame House, the alien arrives and explains to Goku that he is actually part of an alien race called the Saiyans and that they are brothers. Raditz, the Saiyan, requests Goku to join him and destroy everyone on the planet. Goku declines, so Raditz takes Gohan and flies away.
