Plot
Three years after the events of  Come Along with Me , the Kingdom of Ooo was now at peace. In the beginning, Finn has turned 20 years old and now, he and Jake live with his parents in their rebuilt treehouse that got destroyed by a horrendous creature. And for Princess Bubblegum and Marceline, they' re still hanging out with the ladies. So, basically, everything is back to normal after Betty merged with the GOLB and departed from Ooo, saving Simon. The next day, Finn and Jake go out for a walk and they meet the future adventurers, Shermy and Beth. After they meet each other, Shermy and Beth told Finn and Jake that they are their biggest fans. Then, Finn and Jake meet up with the princesses and Marceline and they all start to relax outside on the grass. While they relax, the Kingdom of Ooo celebrate the day Betty saved Ooo from the GOLB.

Finn thinks his years of saving Ooo is over because it is finally at peace. When suddenly, Finn and his friends notice the sky becoming dark and gloomy. Then, a new villain named Lord Grim arrives from nowhere. During arrival, everyone in Ooo gathers as a crowd to meet this unknown stranger. Grim then asks for a way to open a wormhole, but then, everyone realizes he's trouble. So, Finn and his friends fight him with every weapon they got. But nothing worked because Lord Grim was more powerful than him and he used his power to make Finn hand over The Enchiridion. However, his action accidentally opens up a wormhole, which Princess Bubblegum kicks Grim, but then, Lord Grim reveals that he actually wants revenge on Finn about his father's defeat by kidnapping Princess Bubblegum and orders the monsters, including his sidekick Me-Mow, to attack them, but the heroes escape.

The next morning, as Finn and the others come with a plan to save Princess Bubblegum and the Kingdom of Ooo, Jake and Marceline decide to visit Gumbaldia to ask for the kingdom's help. They meet with Aunt Lolly who now rules the candy city, Gumbaldia. While Finn went for a walk to come up with an idea, he meets a failed actress Brenda, and immediately falls for her, something that he thought was impossible as he had never already loved before.

With no other option, they tried to give up, at least until Finn shows up with Brenda, the magic woman. Grim learns of Finn's survival and forms an alliance with numerous past villains from throughout the series who have been reborned, including some new villains, in preparation for the final battle. Before the war, Lord Grim sees that Finn has come back with his friends, along with The Enchiridion. After arrival, Brenda greedily betrays Finn by taking The Enchiridion from him and giving it to Lord Grim and then, Grim destroys the Candy Kingdom, and creates a new kingdom with an army of undead warriors, the Four Demon Kings, brings his dad, the Lich, back to life, along with the previous villains from the series, who are reborned, and also kidnaps Prince Gumball and banishes Finn, Jake and his friends out of Ooo.

While lost in the forest as began to snow, Finn is attacked by the wolves, but his friends save him and take him to the Igloo. While taking him to the Igloo, they met Fionna, who is banished out of Aaa, along with Cake, and Finn's friend, Simon, immediately falls in love. Meanwhile, as Candy Kingdom is now under Grim's control, Lord Grim approached the mystery villain to collect revenge on Princess Bubblegum. Me-Mow and Brenda arrived their master and said what Princess Bubblegum is believed to be Finn's weakness and Finn not renounces be a hero yet. But Lord Grim is never to worry, but he said soon Princess Bubblegum will be Grim's greatest weapon, which will lure Finn back in Ooo to surrender.

After challenging several dangers, as the evil witch, the abominable snowmen and the Eagle, Finn is kidnapped by evil versions of Flying Lettuce Brothers, Gareth, and Tiffany, who create a evil-like version of Jake to finish him. After the fight, Jake takes down the evil versions of his old gang and saves Finn from the certain death. Now, the heroes rush back to Candy Kingdom to stop Lord Grim from taking over. Back at Candy Kingdom, Finn see Princess Bubblegum held captive, who is also used as Grim's greatest weapon. Lord Grim makes Finn choose what to do: Either surrender or see Princess Bubblegum be trapped in a prison bubble? So, Finn dropped his weapon and surrendered, much to Princess Bubblegum's discomfort. Lord Grim finally creates a evil plan to take over Candy Kingdom full of undead creatures and monsters, while also trapping Princess Bubblegum in a prison bubble, even though Finn surrendered, and eventually betraying Brenda because he used her. But then suddenly, the entire multiverse appears, which includes: the farmworld heroes, the land of Aaa, the Guardians of Sunshine video game version of Finn and Jake and the minecraft versions of the heroes. And Flying Lettuce Brothers, Gareth, and Tiffany join the battle to fight against Lord Grim and his army, but Jake asks why they're the good guys because he thought they were evil, but Tiffany explained the whole thing by telling Jake that after he saved Finn and ran back to the Candy Kingdom, he and the others saw the evil versions of themselves and attacked them, which gave them enough time to summon the multiverse, which explains why the entire army of the multiverse appeared to help the Candy Kingdom battle against Lord Grim and the chaos creature.

As the chaos creature, four demon kings and undead warriors attack, Finn sends Princess Bubblegum's Gumball Guardians and the multiverse to fight them, while Lolly assists with Gumbald's giant robot, and Brenda tries to redeem herself by assisting with using her magic powers. The creature overpowers everyone and seemingly crushes Gumball, enraging Marceline and Marshall Lee, who assume more powerful forms and kill it. Gumball revives, and he hugged Marceline and Marshall Lee because they saved his life. The chaos creature then forms again and heads towards the treehouse. Jake witnesses the creature destroying his and Finn's tree house, and becomes despondent. BMO finds him and sings a comforting lullaby to him. The song's harmony negatively affects the chaos creatures, since the Lich's power is derived from chaos itself. Finn encourages everyone else to sing the song again because it worked on the four legged monster in "Come Along With Me", further weakening Grim's monsters, along with Bad Jake and the other villains that were brought back to life by Lord Grim.

After the battle, Finn, Brenda, and Simon try to break Princess Bubblegum free from the prison bubble, and uses The Enchiridion to summon a portal that sucks Lord Grim, his army and Me-Mow into it. With enemies gone, Candy Kingdom goes back to normal and Brenda has redeemed herself. Finn was proclaimed as a hero and Brenda restores the love relationship with Ice King, apologizing him for her behavior and for using him just like Lord Grim used her. As Ice King and Brenda's love relationship is restored, Finn leaves his friends and family and the Tree Fort, just before he grows up, with his friend, Princess Bubblegum.

BMO concludes the story, saying everyone else "lived their lives", and bids farewell to the audience.

During the credits, a montage with the song "Come Along with Me" is shown, revealing the future of the characters, including Gunther breaks the fourth wall and marries Turtle Princess and have two kids, while Marceline moved with Princess Bubblegum. Shermy and Beth were thinking of starting a new adventure of their own, promoting Shermy to say, "What time is it, Beth?" and they both said in unison, "Adventure Time".
