Mick takes the Waverider and Kayla to try and find Sara, but these enemies find themselves needing each other to survive after landing on the possible planet Sara is being held captive. After a report of an Alien attack, the Legends return to their new headquarters where both Spooner and Astra try to connect to the Alien. Meanwhile, Sara devises a plan to escape by using her charm to win over Bishop.

With Constantine obsessed with getting his powers back, he convinces Spooner to join him on the quest to find the Fountain of Imperium. After they find themselves at the end of the Spanish Civil War, Spooner makes an unexpected bond with someone she feels the need to protect. Meanwhile, Sara and Lita are concerned about Rory's health, so they try to convince him to take it seriously.

The Legends are ready to get back home, but after Constantine overloaded Gideon, they are going to have to go the old fashion way to preserve the ships energy. Trying to entertain themselves, tensions start to grow high, so Gary suggests playing a murder mystery game to pass the time. Meanwhile, Rory and Gary deal with an unexpected guest that arrives on the Waverider.

When Sara realizes Bishop's plan, Ava convinces Sara to allow the Legends to make exception to the rules to help fight back. Behrad comes up with an interesting plan, that allows Sara to connect with an old friend. Meanwhile, amidst a battle Sara and Ava make an important decision but need the help of the team to pull it off.

With Astra, Spooner and a now-human Gideon trying to save the Legends, Gideon becomes overwhelmed by her new human choices sending her into a catatonic state. Astra and Spooner combine their powers to enter Gideon's mindscape and discover that a virus is trying to erase all of Gideon's memories. Acting fast, they devise a plan to defeat the virus before it's too late. Meanwhile, the Legends are about to go up against a powerful new foe.

When the Legends and Gwyn finally time travel, the time machine goes haywire leaving them stranded in a lush forest with no idea when or where they are.

Meanwhile, unbeknownst to the Legends, someone keeps trying to destroy the anomalies that keep popping up which could create bigger ripples throughout history.

Behrad seeks advice about Astra from Nate and Zari but Behrad finds that his past is put on display instead.

Trying to help, Gideon negotiates a deal to save the Legends but to get them to agree, she breaks a major rule. Meanwhile, the Legends come up with another plan that could potentially solve all their problems.
