After defeating the Legion of Doom, DC’s Legends of Tomorrow face a new existential threat created by their actions at the end of last season. By revisiting a moment in time they’d already participated in, they’ve essentially fractured the timeline and created anachronisms all across time! Our team must find a way to return all the anachronisms to their original timelines before the time stream falls apart. But before our Legends can jump back into action, Rip Hunter and his newly established Time Bureau call their methods into question and disband the team. Challenging the Time Bureau’s authority, they recruit a hacker from the future, Zari Tomaz (Tala Ashe) and continue their time travelling shenanigans, while insisting that however messy their methods may be, some problems are beyond the Bureau’s capabilities. Some problems can only be fixed by Legends.
