Plot
The player begins the story as Kris, a human child living in a village mostly made up of monster residents, with their adoptive mother Toriel, who is also a monster. Toriel drops Kris off at school, where Kris attends a class taught by Alphys. Kris and Susie, a delinquent monster classmate, are sent to get chalk for the blackboard. Upon entering the supply closet, both of them are pulled into the "Dark World". There, they meet Ralsei, a prince of the dark, who tells them that the three of them are heroes destined to close the Dark Fountain (a geyser of dark energy) to restore balance to that world. However, the King has seized control of the Dark World and is determined to spread darkness.

Susie chooses not to help, only wanting to return to her own world. Before she can leave, the three encounter the King's son Lancer, who tries to stop them from proceeding with various poorly thought out plans. Susie eventually decides to join Lancer, leaving Kris and Ralsei on their own. As Kris and Ralsei make their way to the King's castle, Susie befriends Lancer, and the four ultimately become a team. Upon realizing that they will have to confront the King, Lancer runs off to the castle and arranges for the King's henchmen to throw Kris, Ralsei, and Susie into the dungeon.

Susie escapes the dungeon and confronts Lancer, who explains he wanted to keep Susie and the King from hurting each other. Susie promises Lancer she won't hurt the King. Kris, Susie and Ralsei go to the top of the castle and confront the King in battle. Eventually, the King falls to the ground in exhaustion and Ralsei takes pity on him, healing the King. However, this is revealed to be a ruse as the King quickly incapacitates the three heroes, threatening to kill them all. If the player has resolved enemy encounters without violence throughout the game, Lancer turns the King's men against him and imprisons him, taking his father's place as king of the Dark World. Otherwise, Susie subdues the King using Ralsei's Pacify spell.

Kris closes the Dark Fountain so that they can return to their own world. There, Susie says goodbye, expressing interest in returning to the Dark World. The player can explore the town before having Kris go home to bed. That night, Kris shakes in bed, then falls on the floor and limps to the center of the room. Kris tears into their chest and rips out their heart-shaped SOUL, throwing it into a birdcage in the corner of the room. The player can move the SOUL around inside the birdcage, but cannot do anything else. Kris draws a knife and turns toward the viewer. They smile, with their right eye flashing red.

Development
In February 4, 2031, Phil Lord, the co-developer of the Indie Initiative, said at the San Diego Comic Con said they had thoughts of adapting Toby Fox's sister game Deltarune, which served as the "spiritual successor" to Undertale. Lord and Christopher Miller said to The Verge that the film would be a bit more darker than the previous installments and also will be having full animated sequences, due to the nature of the game being edgier than Undertale. Shortly after, the film were officially announced by Sony on March 28.

The producers hired 3 directors to work on the movie, due to the movie having both live action and animated sequences. First, they hired J. A. Bayona on April 21, who had previously directed A Monster Calls and Jurassic World: Fallen Kingdom, who was going to direct all the live action sequences. Then Genndy Tartakovsky, the creator of Samurai Jack and director of the Hotel Transylvania movies, was hired to direct the animated sequences the next month. And finally, Madeline Sharafian, the director of the Pixar SparkShort Burrow, was announced to be the co-director.
