Starfire and Cyborg have been turned into teenagers, while Argent and Damage have been turned into adults. The rest of the Titans, however, are unaffected. They head to S.T.A.R. Labs to try to find some answers, and Nightwing remembers that he, Arsenal, Tempest and Troia were exposed to an anti-youth serum the Contessa was trying to steal several years ago. But before they can make an antidote to restore everyone to their proper ages, the team is called away to battle the Wildebeest Society.
