After Meicoomon's shocking betrayal, the Chosen Children are reeling. Koushirou Izumi is resolute in uncovering the source of Meicoomon's infection, while Takeru Takaishi faces a grim reality as his partner, Patamon, shows similar troubling symptoms. As they grapple with this crisis, a message from the enigmatic entity Homeostasis warns of imminent world destruction. To avert this catastrophe, Homeostasis proposes a drastic solution—a complete reset known as the 'Reboot' to purge the Digital World of the infection. However, this plan comes with a heartbreaking caveat: all Digimon, including their cherished partners, will lose their memories. With time running out, can the Chosen Children thwart Meicoomon's rampage and preserve their bond with their Digimon, or is their fate sealed by forces beyond their control?
