A strange extraterrestrial species known as the Boazan Forces has attacked Earth seemingly out of nowhere. A group of people who have been properly trained to deal with this type of event has been released. The pilots of the Choudenji Machine Voltes V (5), Earth's defense against the Boazan and their terrifying Beast Warriors, are Kenichi, Ippei, Daijirou, Hiyoshi, and Megumi. The narrative intensifies as the Go Brothers learn their actual ancestry and the circumstances behind their father's abduction. Conflicts and confused emotions impede the Go Brothers at times, but their steadfast resolve to locate their father forces them to return to the scene of the crime. The Voltes Team has another assignment with the support of rebels on Earth and on the aliens' homeworld.
