The team arrives in Norway 1975. They plan to infiltrate a black market arms bazaar, where Savage is likely to participate. Snart, Rory and Ray are eager to go. Rip tries to dissuade them, without success. Along with Sara, they go to the bazaar, and Snart swipes a credential. The guard blocks them, but Stein arrives, convincing him that they are operatives of the Scimitar, and responsible on a number of terrorist acts. The guard lets them in.
Kendra, Carter and Jax are on the roof, ready to provide backup. The team keeps an eye out for Savage, thinking he is one of the buyers (one of the buyers is Damien Darhk with his H.I.V.E. members). However, Savage is actually the seller of a nuclear warhead. The bidding starts, and Savage senses Kendra and Carter are close. He notices the team, and in order to maintain cover, Stein tells Snart to shoot in order to make a bid. And the bid hits to the team. Darhk comes and is suspicious about Stein, but Savage breaks the confrontation. The team tries to maintain their cover, but when Stein tries to suspect Savage about not being able to create a working warhead in "this era", Savage realizes they are impostors. Jax tells Kendra and Carter to prepare. Savage offers 25% discount to anyone, who will bring them the team's heads, and a fight breaks, when Rory attacks. Ray joins the fight from Stein's pocket. Savage watches the fight and Kendra and Carter encounter him directly. Savage activates the warhead. Jax and Stein merge. Sara informs about the bomb, and Ray flies inside to try and disarm it. But the timer counts down to 30 seconds as soon as he does. Firestorm takes the warhead away to let it detonate and absorb the blast. They succeed.
The team returns to the Waverider, and Rip is not happy, as the team has now exposed themselves to Savage. On top of that, during the fight, a piece of tech from Ray's suit was cut loose, and Savage found it. With it, Savage can now build a greater weapon than a nuclear bomb, and a result is that Central City will be destroyed in 2016.
