Mt. Weather

On their quest to find the thumbprint of the President of the United States, the gang heads to Mt. Weather, Virginia, where the government has gone to wait out the apocalypse in a secret underground bunker. When they approach a vehicle with the Presidential seal on it, the person they THINK is the President turns out to have been eaten by his own secret service detail. So there's no thumbprint or even a hand. But it ALSO turns out that this dude is the President's husband. The President is still alive!  

The gang makes their way into the underground bunker and basically kill what's left of zombie Congress. Finally, the gang comes across the President, who knows her husband is dead and has two Secret Service agents, both named Agent Johnson. Also, it turns out that the current President has no thumbs. A few days prior, that creepy old dude from Zona turned up and took her thumbs.  Seems he’s not the only one who knows how to shut down black rainbow. So, now it turns out that they need the thumbs of the President from when the apocalypse started: Bill Carney. He's a Zombie now and he's 25 levels down. Before the team set off to find the President, they are shown a video about Black Rainbow and learn that it's an oldy-timey Cold War era weapon that rains down flesh-eating bacteria and rids the world of all people.

And so, as per usual, our gang constructs a pretty serious plan. They're going to bring the zombies in and kill them one at a time until they find the one they're looking for. Sounds simple. And that’s when they realize that Warren is missing. Following a hunch, she’s made her way further down to the zombie bunker. What does she find? No, not more canisters. She finds the President they actually need.

With the old President in tow, the gang heads off and Warren mentions that they'll be going off to stop Black Rainbow. That’s when the current President turns on them and the Secret Service pull guns. As Commander in Chief, the President tells Sarge to assist Johnson and Johnson in taking Operation Bitemark prisoner. Sarge is torn: she loves Operation Bitemark, but she’s also a marine and she took an oath.

Finally, the gang learns that the President is hell-bent on the reset. She's headed to Zona and taking Sarge with her. At the last minute, Sarge realizes that she can't obey the order, and murders the President.  10K and Sarge take out the zombie Secret Service agents, and as Warren kills the zombie version of the President, she sees another vision of the black rainbow. She knows where to go now: it's Washington DC!
