When the Legends discover a new Encore, Sara, Rory and Ava end up crashing a high school reunion to attempt to stop a serial killer from finishing unfinished business. The Legends devise a plan to send Nate, Ray, Nora, Behrad and their hostage Zari, back in time to try and intervene in order to try to save everyone including them. Meanwhile, Constantine is annoyed that Charlie has been squatting in his old home, but it might be the blessing in disguise they were not looking for.

Ray plans a date night for him and Nora, but all goes awry when an Encore shows up making the team think on their feet and create a lie to keep the Encore at bay. While trying to fool the Encore, Ava learns what Sara was really doing while she was away and confronts her. Charlie and Constantine make a deal to work together, which will benefit both of them. Meanwhile, Rory is upset when he gets negative comments about his book, so Zari helps track down who the critic is, and Rory gets more than he bargained for.

Sara, Constantine and Charlie find themselves in British Columbia searching for another piece of the Loom, but they run into a problem they couldn’t have foreseen. Zari has been having trouble feeling like herself, so she goes on meditative journey at the suggestion of Behrad. Meanwhile, Ava volunteers to try and help Rory with a personal problem.

After Charlie does the one thing that goes against her nature when it comes to her sisters, she tries to protect the Legends by scattering them in different television shows. Of course, in true Legends style some can’t just be blissfully ignorant and happy but figure out a way to end up messing with the system.
