Four saiyan children, Cuber, Chaiva, Speonitch, and Kailon, are sent to a faraway planet by their mission handler, Ocra, to clear out its most powerful inhabitants. Little do they know, they are actually sent away so they can escape the Genocide of the Saiyans. When they arrive on the planet, their space pods are destroyed almost immediately, stranding them. For several years, the saiyans eliminate the planet's most powerful creatures, until some of Frieza's weaker soldiers arrive. The soldiers attack the saiyans, but are defeated easily. Unfortunately, Zarbon hears of the saiyans' presence from one of the soldiers' scouters, and then sends his current best team to eliminate the saiyan threat.
