After Sara's encounter with Mallus, the Legends are paid a visit by John Constantine, a demonologist detective. The Legends agree to accompany him to a present-day psychiatric hospital and they are surprised to discover who Constantine is trying to help. During the exorcism, Sara, Leo and Constantine go missing, leaving Ray and Zari to try to take care of Constantine's client. Meanwhile, Amaya and Nate once again come face to face with Kuasa.
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?
