When a new blip lands the Legends in 1947 Los Angeles, it puts them on the trail of Benjamin "Bugsy" Siegel who seems to take pleasure in fraternizing with Hollywood Elite. Sara, Ray and Constantine devise a plan to capture him while Ava and Rory sit on the sidelines for the time being. They soon realize that they need to worry less about Bugsy and more about his girlfriend. Ava is struggling with being on the sidelines with Rory. Meanwhile, Nate accompanies Behrad to his dad's birthday, where Nate meets Behrad's sister, Zari, who seems familiar to him.

When Sara is called away on business, she leaves Ava in charge and Ava tries to impress the team as they try to take on their latest Encore, Marie Antionette. With Zari still on the ship, Behrad convinces the team to bring her along on the mission which they all hope isn't a mistake. Meanwhile, Constantine finally confronts someone from his past with the help of Charlie, which leads him on a journey through his past.
