Film Summary

Plot
Finn having a dream about the Lich-possessed snail using the Enchiridion to attack Billy causing him to awake and frantically tells Jake about his dream, who—after hearing that the Cosmic Owl appeared in the dream—believes it is a premonition. The two go visit Billy, and tell him about the dream. Billy realizes the importance of the dream, and the three of them set out to stop the Lich. After they head out, Billy tells them that they need to collect all the magical gems from all the princesses and Ice King's power crystals that protect them from the Lich. With only one gem left, Finn finds the Enchiridion in Billy's knapsack. Billy reveals that the book has magical properties, and after activating it a certain way, the circle on the front opens up showing 9 slots where all the gems go in, and it shows a brief diagram about what would happen if all the slots were filled.

A holographic being named Booko appears and explains that when all the gems are placed in the book, a portal to the multiverse will be opened. Billy claims that he is going to throw the Lich through this portal. Finn and Jake then set off to get the last gem: Princess Bubblegum's. As Finn and Jake try to take the gem, a scuffle ensues, and the duo manages to get the gem. Once outside, Finn puts the gem in the final slot. Lights start to flash out of the stones on book. Then the book starts to shake while the pieces start to fall off as the Enchiridion turns into a black block. As Finn is running, Billy tells Finn to hurry. Princess Bubblegum then runs out telling Finn that Billy is really the Lich.

Just as she says this, one of the Gumball Guardians gets up, detecting the Lich, and blasts Billy revealing that half of Billy's face is actually the Lich's son, Lord Grim. Grim then asks for the book, but Finn smashes the book with his knee. However, his action accidentally opens up a wormholem, which Princess Bubblegum kicks Grim, but then, Lord Grim reveals that he is actually wants revenge on Finn about his father's defeat and orders the monsters, including his sidekick Me-Mow, to attack them, but the heroes escape.

The next morning, as Princess Bubblegum prepares for war with Gumbald, Finn and Jake decide to visit him to prevent the battle from happening. They meet with the Gum Family who are hellbent on wanting to destroy Bubblegum. Ice King 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, Bubblegum sets to go to war with her uncle. Gumbald learns of Bubblegum's survival and forms an alliance with numerous past villains from throughout the series, including a confused Ice King, in preparation for the final battle upon which Ooo's fate depends: The Gum War. Before the war, Lord Grim kidnaps Princess Bubblegum and 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, and also kidnaps Prince Gumball and banishes Finn, Jake and his friends out of Ooo. Meanwhile, Brenda greedily betrays Ice King, dumps him and banishes him to the forest.

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. Ice King met Fionna, who is banished out of Aaa, along with Cake, and he 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 bad and Finn not renounces be a hero yet. But Lord Grim is never to worry, but he said soon Princess Bubblegum protect her new boyfriend, not until then he was helping for Bubblegum to do not disturb.

After challenging several dangers, as the evil witch, the abominable snowmen and the Eagle, Finn is kidnapped by Flying Lettuce Brothers, Gareth, and Tiffany, who creates a evil-like version of Jake to finish him. After the fight, Jake betrays 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 angrily blames with Princess Bubblegum for holding him back at her uncle's cruelty, breaking her friendship, much to her discomfort. Lord Grim finally creates a evil plan to take over Candy Kingdom full of undead creatures and monsters, finally summoning GOLB. 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 went back to the dark side, 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 have enough 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, Bubblegum sends her Gumball Guardians and the multiverse to fight them, while Lolly assists with Gumbald's giant robot, and Fern assists using his grass powers. The creature overpowers everyone and seemingly crushes Bubblegum and Gumball, enraging Marceline and Marshall Lee, who assume more powerful forms and kill it. Bubblegum and Gumball revive, and she and Marceline emotionally express their feelings for one another before kissing, confirming their long hinted romance and Gumball hugged Marshall Lee because he saved his life when Marceline saved Bubblegum's life at the same time. 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. Bubblegum encourages everyone else to sing the song, further weakening Grim's monsters and arrests Gumbald for his crimes, along with Bad Jake and the other villains that were brought back to life by Lord Grim. But before Gumbald was arrested, he apologized to Princess Bubblegum for his bickering against her and he told her that he should've been more reasonable to Princess Bubblegum instead of going at war with her. Then, he asked her if she could give him one more chance, and then, she told him that she understood him, but what he did was wrong. In the end, she was going to help him redeem himself and was willing to set him free. Then after that, they made peace, and Princess Bubblegum declared "two Candy Kingdoms". After that, they hugged each other and she said "You know, you remind me of Finn when he awkwardly hugs me". And then, she was like "(Gasps) Finn!!".

Meanwhile, Finn, Betty, and Ice King are trapped in a small, shrinking room within GOLB. Grim's influence reverts Ice King to Simon, and Betty to her sanity, while Ice King's crown loses its power. Simon and Betty reconcile, but they and Finn resign themselves to death as the walls close in. Suddenly, BMO's song opens a breach, through which Finn and Simon escape while the heroes fights Grim, which later kills Fern earlier. The fight ends when Betty, however, realizes that the singing has reset the ice crown's power, and so she puts it on wishes for the power to save Simon. This causes her and Grim to merge into a singular entity, destroying the chaos creatures, summoning a portal that sucks Lord Grim and Me-Mow into it. With enemies gone, Candy Kingdom goes back to normal and the ice crown falls to the ground, where it is picked up by Gunter the penguin, who puts it on and becomes a creature that resembles Ice King himself. Finn, being proclaimed as a hero, restores the friendship with Bubblegum, apologizing her for his behavior. As Fern dies, he asks to be planted at Finn and Jake's tree house; the duo do as request, resulting in a new tree containing the Finnsword sprouting from the ground.

BMO concludes the story, saying everyone else "lived their life", and bids farewell to Shermy and Beth. Wanting to know if the story is true, they head to the tree that Fern sprouted, which is now gigantic.

During the credits, a montage with the song "Come Along with Me" is shown, revealing the future of the characters, including the adult Finn breaks the fourth wall, marries Brenda and have two kids. Shermy and Beth reach the top and pull out the sword, assuming a pose similar to Finn and Jake's at the end of the show's title sequence.

Announcement
In February 2015, it was announced that Cartoon Network Studios is developing an animated theatrical Adventure Time feature film and its release date of August 3, 2018 was also announced, with the show's cast reprising their roles. Mike Mitchell, who directed The SpongeBob Movie: Sponge Out of Water, is directing the film, and Kelly Crews is going to be producing the film. In October 2016, it was announced that Warner Bros. Animation will be co-producing the film and Pendleton Ward, the original show's creator, will screenwrite the film and will also be the executive producer with Adam Muto and Fred Seibert. A month later, it was announced that Chris Ayres, Kathleen Barr and Whoopi Goldberg had joined the cast.

Development
Warner Bros. Animation had already begun the process of starting development of movies with budgets of around $100 million. The intellectual property for these films was meant to be supplied by Warner Bros. Animation, Hanna-Barbera (Warner Bros. Animation's in-name only division), Cartoon Network and Turner Entertainment (also both Time-Warner divisions) among others and included The Flintstones, The Jetsons, Scooby-Doo, Samurai Jack, Adventure Time, Cow and Chicken, and more, of course, Codename: Kids Next Door. Cartoon Network had been approaching the original crew from the television series to make a high-profile, animated theatrical feature-length film adaptation and had long wanted to partner with Warner Bros. Pictures to release an Adventure Time film given the network's extraordinary legacy in the world of animation, including some of the most enduring characters on cable television history.

Creator Pendleton Ward agreed to make a feature film version of the show with the promise it would be the first of a planned trilogy. During development stages of the film, he and his producer Kelly Crews and executive producers Adam Muto and Fred Seibert intended to revisit some of the greatest films of the time, with Scarface and The Dark Knight having the core inspirations for the film.
