Watch DC's Legends of Tomorrow

With Ava a wreck, Behrad and the Legends make a last-ditch effort to keep Sara from being abducted in the first place, even knowing that it will alter the timeline. Sara grapples with what she has just discovered about herself but is also shocked when Rory finds her on the mystery planet. With no time to spare, Sara, Mick and Gary devise a plan to help defeat Bishop. Meanwhile, Spooner envisions what her life would be like if she hadn't joined the Legends.

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, Constantine's manor, where both Spooner and Astra try to connect to the Alien. Zari is suspicious of Constantine's behavior, but isn't surprised when she learns the truth. Meanwhile, Sara devises a plan to escape by using her charm to win over Bishop, but she learns something more disturbing.

With Astra now a mortal, she finds it hard to adapt to the real world with no guidance from Constantine. Frustrated and lonely, Astra makes a new friend who promises to help her, but her eagerness for the easy way out could have some real repercussions for those closest to her. Meanwhile, Sara meets the person responsible for her kidnapping and tries to convince others to help her escape.

The Legends are shocked when Rory takes command and manages to find the location of an important Alien, but he also lands them in the middle of the Cuban Missile Crisis. Ava is eager to question the Alien, but they must steal it back from the Cubans and Russians who think it is bio-warfare sent by the Americans. The team makes the decision to split up, leaving Nate and Zari to work together to stop a nuclear disaster alongside JFK while Behrad tries to leverage his newfound friendship to stop Castro from starting a war. Meanwhile, with Spooner's help, Rory makes an unlikely deal that could lead him on a solo mission to find Sara.

The Legends find themselves in 2045 trying to defeat an Alien warrior which leaves Zari no choice but to enter a popular singing competition. Ava has finally had enough of Rory's behavior and with the encouragement of Spooner, gives him some tough love. Sara finds herself struggling after being attacked but someone familiar helps her to keep searching for refuge. Meanwhile, Zari and Constantine have a much-needed conversation with each other.

With Spooner on board, Ava hopes that her special abilities will help lead them to locate the Aliens spread out on the timeline, which could ultimately lead them to Sara. The Legends soon find themselves tracking an Alien in 1950s San Bernadino and having to figure out what is making the town go on a feeding frenzy. Zari lets Behrad know she is ready to use the Totem, but Behrad isn't ready to share it, causing tension between them. Meanwhile, after crash landing, Sara tries to figure out a plan and runs into none other than Amelia Earhart who could be her ticket home.

After a night of celebrating their beating the Fates, the Legends quickly discover that Sara is missing. Trying to keep it together, the Legends are shocked to discover that she was taken by Aliens. Ava sends Rory and Behrad to follow a lead on who can possibly help them find Sara, while Constantine tries to work his magic. Meanwhile, Sara does all she can to try to escape, which includes releasing Aliens into the timeline, but is shocked to learn who one of her kidnappers turns out to be.
