While Sara is still away from the Waverider, the Legends use Ava's new invention, the Prognosticator to find a new Encore and defeat Genghis Khan in 1990s Hong Kong. Constantine's life is in danger and Ray, Nora and Gary all try to help him. Meanwhile, Behrad has been confused about Charlie's recent behaviour, but they all learn what Charlie is running from.
When heroes alone are not enough... the world needs legends. Having seen the future, one he will desperately try to prevent from happening, time-traveling rogue Rip Hunter is tasked with assembling a disparate group of both heroes and villains to confront an unstoppable threat - one in which not only is the planet at stake, but all of time itself. Can this ragtag team defeat an immortal threat unlike anything they have ever known?
