Trailer
After the defeat of the immortal villain Vandal Savage and the exposure of the corrupt Time Masters, a new threat emerges. Dr. Nate Heywood, an unconventional and charming historian, is thrust into the action. After making a shocking discovery, Nate seeks out Oliver Queen for help in finding the scattered Legends. Once reunited, the Legends continue their new mission to protect the timeline from temporal aberrations - unusual changes to history that spawn potentially catastrophic consequences. Their first stop is 1942, to protect Albert Einstein from being kidnapped before the Nazis destroy New York City with a nuclear bomb. Meanwhile, Ray notices that Sara has a mission of her own, which leads them both to face her nemesis, Damien Darhk.
