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? <p> 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!
