When the Legends realize that they broke the timeline, Rip Hunter arrives with his new organization - the Time Bureau - to relieve them of duty. The Legends are thrilled to get a chance to put the team back together but a new threat arises when Rory spots Julius Caesar in Aruba. Sara, Nate and Ray devise a plan to steal the Waverider back from the Time Bureau in order to try and stop Julius Caesar from conquering the modern world.

The Legends plan to vanquish Mallus by using the totems doesn't go as planned, forcing Rip to improvise. The team finds itself regrouping in the Wild West where they run into their old pal Jonah Hex. Sara leaves Ray in charge of watching Damien Darhk, while she comes up with a new plan. Meanwhile, Amaya is determined to find a way to use the totems to destroy Mallus.
