Rattled by recent events, the Legends dive into work which finds them investigating an Anachronism in a Viking settlement in the New World. The Legends realize that the Norsemen are worshiping an artifact as their god and are surprised by the artifact's origin. For the first time, Sara is worried that they might need back up when Damien Darhk shows up. Meanwhile, Jax finds a loophole that could potentially change history, but it is a risk he is willing to take.

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.
