As the Smith family go to Church on Christmas morning, Stan is frustrated dealing with those that are only religious on holidays. To relieve Stan's stress, Francine has sex with Stan in the janitor's closet as the world ends, leaving them and Roger on earth as Hayley and Steve float up to heaven. Stan and Francine find out about what coming days will be like and ponder their fate. Steve and Hayley are escorted to their own personal Heavens by Michelle, Steve finding out his is a virgin riding a unicorn that poops pepper-jack cheeseburgers. Stan finds out that Jesus will be appearing and tries to blame Francine for getting left behind. Francine becomes angry and leaves Stan, meeting the real Jesus in a diner. Stan finds out that his Jesus is fake but when he tries to make up with Francine she has decided to leave Stan for Jesus.
During the Seven years or the Tribulations, Stan has found himself a bitter, scarred and no longer willing warrior for Christ. Jesus seeks him out to let him know that Francine has been captured by the Anti-Christ. Stan reluctantly agrees to help rescue Francine in exchanged for being Raptured to Heaven. They need to get Roger to use his spaceship to fly them to New York and the United Nation's Building to confront the Anti-Christ which they are able to re-power using The Golden Turd. They rescue Francine but fall into a trap from which they manage to escape but not before Stan is mortally injured. Francine finds that Stan still keeps their wedding rings and realizes he still loved her.
Stan dies in the explosion and is sent to heaven; when guided to his "personalized heaven" we see that it is his home just as it was at the beginning of the episode, the only difference being Klaus' dead fish body being mounted on a plaque hanging on the wall.
