After a quick recap of the previous episodes, reveals that he is about to close a deal to buy back. Unfortunately, he fell for another obvious scam, and Earth looses its final bit of money. The populus is forced to evacuate the planet. Ships at South Street Spaceport carry people to different planets in the solar system, with the Planet Express Ship bound for Neptune.

Back in the past again, has  placed in a tank on the ship. Leelu seems forelorn and distraught and won't eat or play with Fry. Fry then sees a male narwhal swimming outside the ship (this one with an orange-colored skin) and thinks that he is upsetting her, so he steers her away from him.

On Neptune, the Earthicans encounter, who is too depressed for murder and mayhem, as the scammers have also scammed him. But, having become hardened by her failed relationship with , decides it is time to fight back.

A strategy is proposed, but it is revealed that the scammers have used the money to build several remote-controlled solid gold Death Stars. Robot Santa reminds them that he still has elves to build weapons, so he gets together with his friends the Kwanzaa-bot and the Chanukah Zombie. Through song, their weapons are soon built, and they are ready to attack, being lead by Zapp Brannigan, whose plan is to send in a brigade of children first to buy them a few seconds. As they approach Earth, one of the Death Stars shoots down the Nimbus (though the entire crew manages to survive). Leela takes command of the fleet, but is soon overwhelmed by the complexity of directing so many ships. uses his vast knowledge of bureaucracy and organization to control the entire battle smoothly (with the help from the, who wires his head into the mainframe). Soon the battle is won, and Hermes wins back for good. But the scammers have one final trick up their sleeves&mdash;they reveal the bag that they stole from the Professor. gives them 30 seconds to decide on an ultimatum.

, having revealed that he was the one who cut off the Professor's hand with an extremely dull saw, makes a modest apology to the crew for what he has done. But to their surprise, this is a ploy to distract the scammers as he also reveals that he has the bag with the actual doomsday device, and that the scammers have been scammed. They fire off the device and destroy the scammers' ship. Bender explains that this was planned as he was stealing the device, and he stole the device for himself to use later as soon as he was released from the scammers' control.

At the New Year's Eve celebration, Bender is awarded the Dirty Double Cross, Earth's highest honor in swindling, for saving the world. Lars comes and gives Hermes' his body back, fully repaired. Leela is still heartbroken about the incident at the wedding, and that Lars tries to avoid contact with her. Fry, unable to see Leela unhappy any longer, tells her to meet him at.

In 2012, Fry realizes that Leelu is actually in love with the male narwhal, and decides to set her free, in his words; "I want what makes you happy, not what makes me happy."

Back in real time, Fry secretly invites Lars as well, as he, like his duplicate self, has decided he wants what makes Leela happy, unknowingly coining his duplicate's phrase. But as Lars is trying to explain to them both why he and Leela simply cannot be together, Nudar enters, having survived the explosion thanks to a doomproof platinum vest (the closest thing to clothing he is seen to wear). He says he wants the, but Fry and Leela stress that removed it from him. However, Nudar isists that Lars has it. Nudar threatens to kill Leela for the code, but Lars instead goes to the tube with the Bender duplicate in it and opens it, dragging Nudar onto Bender with himself. Bender explodes, killing himself, Nudar and Lars. In her horror and grief, Leela rushes to Lars' smoldering body, only to see that he has the same tattoo on his backside as Fry...

Back in 2012, Fry is entering his home above when Bender comes around and destroys it. The initial blast doesn't kill Fry, but Fry's hair is burnt off, his beard shortened, his skin darkened, and his larynx damaged; he sees himself in the mirror with his new appearance and deeper voice and realizes that he is Lars. He rushes to the Applied Cryogenics lab, and gets in a tube (containing his old girlfriend Michelle), setting it for 990 years. Waking up in 3002, he gets employed at the head museum.

At Lars' funeral, it is explained by Lars in a video will that he waited for the day Leela would arrive. When he saw Hermes' body destroyed at the wedding, he realized that as a, he himself was doomed, and would not put Leela through having to deal with his death. Fry says that he was a good man; Leela agrees, and kisses Fry on the cheek. Everyone is reminded that in order for any of this to make sense, someone must travel back in time for one last time to tattoo Fry's backside in the first place, so Bender volunteers, peeling the tattoo off of Lars' corpse and going back in time.

Back at Planet Express, Bender comes up from the basement and says that he has done the job. He then says that he met all his own copies down in the basement, and told them to stick around instead of come up when they logically supposed to. This creates an extreme amount of duplicates. Nibbler fears the worst, and using an as-yet unseen ability, consumes himself; presumably, the high-density compression of his digestive tract allows him to teleport to an unknown dimension. As each duplicate explodes one after the other, a massive rift in time and space appears before them. Bender sees this and ends the with, "Well, we're boned."
