Bulma is arrested by a mysterious group of militant, heavily armed refugees while traveling to Namek. At first, they accuse the trio of being henchmen of the evil Frieza that destroyed their home planet. However, when the Earthlings help in a dangerous situation, the refugees allow them to continue on their journey to Namek. They reach the planet and, with the help of two Namek natives, begin their search and find two Dragon Balls.
