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.

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.
