The scene begins with Frisk, a human child, wanting to go outside despite Toriel's warnings. Meanwhile, Asriel, a monster, is struggling with his past and the influence of Flowey, a manifestation of his darker emotions. Flowey tries to convince Asriel to abandon his emotions and rely on his powers, but Asriel resists, believing that his emotions and connections with others are what make him strong.
Gaster, a scientist, is questioning Undyne about her battle with the creature, and it is revealed that the creature gained a power boost from a mysterious vial. Papyrus, a skeleton, tries to comfort Gaster, who is struggling with forgiveness and his past mistakes.
Asriel is eventually consumed by his inner demons and merges with Flowey, becoming a powerful and menacing entity. Frisk and other characters, including Papyrus and Sans, try to stop him, but Asriel's powers prove to be too strong.
In the end, Asriel is defeated, but at a great cost. Papyrus is severely injured while trying to save his brother Sans, and Asriel's soul is taken by the creature. However, Frisk and the others discover that they can bring Asriel back using the power of love, which is the opposite of hate.
