Kansas City

Dean arrives in town and avoid a man handling out religious tracts. Once he checks in, he contacts Castiel who believes that the demons haven't yet melted down the Colt. The angel believes that if Dean still plans to carry out his plan to kill Lucifer, he'll need the Colt. Castiel is ready to move but Dean insists on getting a few hours of sleep before they proceed.

Later, Sam calls Dean to inform him that he's Lucifer's chosen vessel. Dean isn't particularly impressed and wonders what Sam wants to do about it. Sam wants back in so he can redemption and plans to prove it to his brother. Dean tells him that it doesn't matter and they should stay away from each other for good. If they try to work together, the demons will use their family bonds against them. Dean hangs up goes back to bed.

The next morning, Dean wakes up to find himself lying on a ruined bed in a collapsing hotel. He looks outside and sees that the streets are filled with devastation. Dean goes out onto the deserted street and searches around. He finally hears a noise and finds a little girl crouching in the street. Dean approaches her and she grabs a piece of broken glass and stabs him. Dean knocks her out and sees the word "Croatoan" written on the wall. A dozen zombies walk around the corner and chase Dean through the streets. He come to a fence and the creatures closed in. However, a squad of soldiers show up and gun down the zombies.

That night, Dean gets through a fence and finds a sign identifying the area as a Croatoan Virus hot zone. The date is August 1, 2014. He steals a car and tries to get anything on the radio or cell phone. Zachariah appears in the car and reads the newspaper, revealing that what's left of Congress has declared martial law. The angel managed to find Dean using human informants among the fringe Christian groups. Zachariah tells Dean that he's giving him three days to see what the consequences of his actions are if he continues to say "no" to Michael. Zachariah disappears and Dean goes to visit Bobby. He finds his friend's overturned wheelchair covered in blood and bullet holes. Dean checks Bobby's journal and finds a photo of him at Camp Chitaqua with other hunters.

Dean goes to the camp and finds a hunter compound. He sneaks in and finds what's left of the Impala, and someone knocks him out: his future self.

Dean wakes up a prisoner and Future Dean has already confirmed that he has everything that Future Dean has. Dean explains that Zachariah sent him from 2009 but doesn't know where the angel is now. Future Dean wants evidence Dean is who he says and Dean describes a Rhonda Hurley who made them try on her pink panties. Future Dean is convinced and explains that two years ago there was an outbreak of the Croatoan virus and Sam was destroyed in a major showdown when Future Dean wasn't there. Future Dean leaves Dean chained up so he doesn't upset the camp full of traumatized survivors.

Dean eventually picks loose a splinter and uses it as a lockpick to free himself. He goes out and Chuck Shurley, mistaking him for Future Dean, comes over to review their supply lists. Dean tries to bluff it out but Chuck starts to catch on. However, a woman, Risa attacks Dean and wonders if he was sleeping with another woman the previous night. She storms off and Dean asks where Castiel is. Chuck directs him to a cabin where Castiel has gathered a group of women and is teaching them that the key to shared perception is an orgy. Dean comes in and Castiel realizes that he's from the past. Dean wants Castiel to send him back but Castiel explains that life happened to him and he's now perpetually stoned.

Future Dean brings a convoy of jeeps into the camp and the men share a beer. Future Dean then shoots one of them down as Dean tries to stop him. Future Dean tells his men that something is going on and he'll tell them when they need to know something. He then shoves Dean back into the cabin and explains that the man he shot, Yager, was invaded during a Crote attack. Future Dean insists that it's a common occurrence in 2014 and Dean is in no position to make decisions. Dean apologizes and Future Dean pours drinks and explains they were on a mission find the Colt. The demons have been moving it around for five years but Future Dean finally got it. Tonight he plans to kill Lucifer with it.

Future Dean shows the Colt to Risa and Castiel and explains that they caught one of Lucifer's entourage and confirmed he wasn't lying. Dean is surprised that Future Dean is torturing again. Future Dean ignores him and shows them the hot zone where Lucifer has his headquarters. Castiel agrees but wonders why Future Dean is taking Dean. Future Dean refuses to hear any argument and orders them to be ready by midnight. Once they're gone, Dean wants to know what's really going on and Future Dean explains he wants Dean to see Sam. Sam said "yes" to Lucifer. Future Dean tells Dean to say "yes" to Michael. Dean warns that the battle will torture half the planet but Future Dean insists he'd agree in a heartbeat, but the angels gave up and it's too late for him. He admits that he was wrong and begs Dean to agree. However, he realizes that his past self won't because it's just not either one of them.

As they leave, Chuck offers Dean some advice to hoard toilet paper. As they drive, Dean sees Castiel taking amphetamines to counteract the absinthe. Castiel admits he became mortal after the other angels left the planet. He figures he has nothing to lose by burying himself in decadence before the lights go out for good.

Come morning, the team arrives in town and proceeds on foot toward Lucifer's headquarters at a sanitarium. Future Dean insists that the demons will never see him coming. Dean talks to him in private and wants to know why Future Dean is lying. When Dean threatens to take his concerns to the others, Future Dean explains that there are no Crotes and Lucifer has set a trap. Future Dean plans to have the others go through the front while he and Dean go through the back. When Dean objects, Future Dean says that his weakness was what created the Apocalypse. When Dean tries to stop him, Future Dean knocks him out.

Dean wakes up to the sound of gunfire within the sanitarium. He runs inside and finds a white-suited Lucifer in Sam's body snapping Future Dean's neck. Dean invites Lucifer to destroy him but Lucifer doesn't see the point. He apologizes for the surprise and admits he had to use Sam's body. Lucifer assures Dean that he has nothing to fear: he has no intention of destroying the planet. He explains that he rebelled against God when God asked him to bow down before the humans and love him more than God, and Lucifer refused because they were murderous apes. Dean insists he knows what Lucifer is and says he's the same brand of monster he's been killing his entire life. When Dean defies him, Lucifer admits that he likes him and they'll meet again. Dean vows to kill him but Lucifer says he knows that Dean will always refuse Michael and refuse to kill Sam. Lucifer assures him that inevitably they'll end up there and he wins. Dean insists he's wrong but Lucifer simply smiles and says they'll meet in five years.

Zachariah returns Dean to his hotel room in the present. The angel insists it's no trick and Dean must surrender himself to Lucifer before he gets to Sam and billions die. Dean considers the matter and then tells him no. When Zachariah insists on teaching him a lesson, Dean disappears thanks to Castiel. Dean tells Castiel not to ever change. Dean then takes out his phone and calls Sam, and arranges a meeting. He takes out the demon-killing knife and gives it to Sam, and says he'll need it now that they're teaming back up again. Dean apologizes for being wrong and admits they may be each other's weakness. However, they're all they have and they keep each other human. Sam thanks him and promises not to let him down. Now they have no choice but to make their own future.
