Following their first encounter with Goku Black, the Saiyan trio are itching to dish out some payback! It's a mystery as to why Black has a Time Ring, so it's off to the Tenth Universe for a discussion with the Supreme Kai and his suspiciously well-mannered apprentice. Meanwhile, Earth's attacker continues to wreak havoc in the future. How could the Kais possibly tie in with someone as evil as Black? Everyone's lives are on the line, and it's up to the Z Fighters to either face the problem head-on or try to alter the timeline at the source!
