After Sara, Ava, Behrad and Gary arrive in New York City, they track down Dr. Gwyn Davies, who isn't the scientist they expected. Astra, Spooner, and Gideon are still trying to stop the Legends from using the time machine, but they run into some more setbacks along the way. Meanwhile, in the pocket dimension Nate and Zari work together on the Hoover situation as well how to make their future together work.

When the Legends arrive in Chicago, they come across a speakeasy that caters to a diverse crowd, however their presence results in upsetting a mob who in turn burn down the club. Wanting to make things right, Zari demands they help to fix the club by throwing a party, with a special performance by The Bullet Blondes, to help raise money to rebuild it. Coincidentally, Astra, Spooner and Gideon are also in Chicago and feel compelled to help a female musician sever ties to the mob, while also trying to reach the Legends.

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.

While the Legends contemplate how to get to New York City, Behrad discovers Hoover has train tickets to DC and Sara and Ava come up with a plan. With Zari stuck without the internet, she is forced to take a digital detox and becomes obsessed with figuring out who blew up the Waverider. Meanwhile, Astra and Spooner have stayed behind in Texas and are dealing with the aftermath of Astra's special spell.

After defeating the aliens and saving Earth, the Legends find themselves stranded in 1925 Odessa, Texas with a destroyed Waverider. Wanting to help fix things, Astra tries using her powers, which creates unwanted attention from the town and that of the new Director of the Bureau of Investigation, J. Edgar Hoover. Realizing they need to escape, Sara and Ava create a distraction by going on a crime spree with Hoover hot on their tails. Meanwhile, Zari is finding it hard to get over Constantine, so Behrad suggests the only thing he knows that can help.

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 the Legends track down another Alien pod, they find a device that transports them to a cosmic bowling alley. Spooner makes a bet against the reigning champs for a ride back to the Waverider, but not everyone is happy about the plan when they realize what they are up against. Elsewhere, Nate plans a romantic date for him and Zari, but nothing goes as planned. Meanwhile, Behrad and Gary try to distract Ava from what's going on with wedding planning.
