Premise
In 2033, street thug Sebastian "Blame" Hernandez arrives in an alternate reality where the United Kingdom has managed to conquer the world and declare world peace. Soon after, terrorist Bobby Worst nukes the planet and causes a global apocalypse, turning everyone into their worst selves. Blame is told by the Eldest Elmer that Blame himself caused the apocalypse through an unrelated chain of events that began in 1865. The eldest Elmer informs Blame that his actions have led to this moment and that he must go back in time to ensure the events never happen. However, the time machine was back at the place where he was abducted by the Society of Elmers. With the help of CEO Bryce Tankthrust, a captive of the Elmers, he successfully finds the time machine and goes back in time, while she stays behind and fends off Bobby, leading to the two of them killing each other. It's revealed earlier that a series of events in Bryce and Bobby's childhood led the latter to turn against her.
Blame begins by going back to 1865, where he stops a British couple who call themselves the Mingeworthies from seizing control of the US. After that, he returns to 2018, when he was a child. As a child, he wanted a tattoo and ended up getting a gang sign. However, this led to women rejecting him, and, while "back in time", he allowed Sam, who, unbeknownst to Blame, is his future foster father. Sam is a flamboyant and colorful person, and, a Christian, decides on a tattoo reading, "I Love Jesus" with a heart. Sooner after arriving, he meets up with another version of him, who was the one who wanted to prevent the tattoo event. He lends his time machine to the original Blame so that he can go back to 2033, while he stays behind to relive his life.
However, the apocalypse has just started once again, meaning his journey was in vain. He heads back to the eldest Elmer in a bunker. There, he is betrayed by Elmer after revealing the whole plot was only to stop Worst from nuking the planet so Elmer could use a chemical weapon to turn everyone on Earth into Elmers. After killing the eldest Elmer for betraying him, he goes to find the time machine, and in the process kills multiple Elmers. He opens the time machine and prompts it to go back to when it was created. However, an Elmer gets possessed by the eldest Elmer and gets a hold of it and ended up being the one taken back in time with Blame.
Both are transported to Germany in 1942. Blame meets a crew of American assassins attempting to kill Hitler. Elmer finds the place where Hitler and two "associates" are and is greeted with much joy by Hitler. These associates are, unknowing to Hitler, 2 of the assassins. Elmer warns Hitler that Blame has come to kill him before his birthday party, leading to stricter security. Blame and an assassin get into a confrontation, with the assassin proposing Blame could want to kill Hitler just to be the only person with time travel. However, Blame denies this and invites the assassin to smoke marijuana with him.
The assassins plan the raid on his birthday party; the 2 assassins who befriended Hitler will be inside and will give a signal for Blame and another assassin to kill the 2 guards, and enter once finished. An assassin takes the waiter's clothes, and they poison the cake. The assassin brings the cake to Hitler, however, Hitler recognizes they are not the same person. The assassin denies this and tries to leave, but Elmer smells marijuana coming from the assassin and shoots him. Punchler, an assassin who befriended Hitler, reveals he was a spy for an unknown reason. He is shot and dies, and Kickler, the other friend of Hitler, attempts to shoot Hitler, but shoots and kills his mother and father.
Elmer searches the kitchen for Blame, finding him behind a table. Blame throws a can next to Elmer to distract him, and then throws another directly at him. Outside, Kickler has Hitler at gunpoint, and his wife and dog show up with guns. She shoots both but is overpowered by Hitler, who takes off her wig to reveal she is not blonde before killing her. In the kitchen, Blame is overpowered and on the ground, and Hitler attempts to shoot him but has no bullets left. Because Blame is overpowered, he summons Abraham Lincoln from the time machine, right before he cures cancer. Because he summoned him, the time machine was on the ground, and a fight between Elmer and Blame ensues. Lincoln and Hitler join in the fight on the sides of Blame and Elmer, respectively. The time machine is hit against a wall in the scuffle and malfunctions, sending Hitler and Lincoln to when Tankthrust proposed to Worst. They intervene just at the point where Worst vomits on Tankthrust's heart, leading to the apocalypse. Worst takes Tankthrust's knife and stabs Hitler, believing it would make his dad proud. However, his dad is unenthusiastic and leaves to change identities, ashamed of his son. This leads Tankthrust to not need a heart, where she says she learned she didn't from Hitler's, "How to Rule A Nation of Stupid People".
Lincoln returns to the fight with the time machine and is stabbed by Elmer, who was attempting to stab Blame. Blame stabs Elmer in the stomach, and Elmer goes down. Blame kneels next to him, and Elmer asks if Blame is afraid of death, to which he says, "When I die, I'm going to hell for life." Elmer replies by shooting him in the head, assumedly killing him. Elmer declares victory and picks up the time machine to go back to the present. However, right before finishing his sentence, he vomits blood, and realizes the knife Blame stabbed him with was poisoned. Lincoln, believed to have been poisoned as well, realizes the knife was not poisoned.
In a hospital room, two assassins stand next to him, revealing in dialogue he is still alive, but likely would have a very altered memory if left alive. One assassin asks the other her name since the war is over. The one who asked reveals her name is "Skinny Bitch", and the other assassin reveals herself as "Donna Phitts", Blame's future foster mother and husband. She is told to euthanize Blame, and she assumedly follows through on it.
Later, Donna and Skinny are seen in a field, with the former giving a eulogy for Blame. In 2020, it is announced that Tankthrust has won the U.S. Presidential Election and the British couple who made America a British nation are seen watching the television, asking what the nation would be like if they ran it, showing that Blame saved America from becoming British. Later, an Elmer is seen in a tattoo parlor, sensing someone is supposed to be there (Blame), but no one appears and he continues to tattoo young Blame. Tankthrust appears with Worst, revealing they worked together to get Tankthrust elected. Later, an old man is seen with an elderly Donna, and, in the last few moments of the episode, is seen covering his gang tattoo with his sleeve, showing that he never changed his tattoo and that he is still alive, meaning the timeline is forever fixed.
