Takuya and his DigiDestined team are traveling through a desert when they find themselves ending up on a floating island known as the Lost Island and in civil war between human and beast Digimon. While ending up on a village of humanoid Digimon, Takuya, J.P., and Tommy learn from Kotemon of a legend that the island was protected by their god Ornismon. Kotemon proceeds to take them to a neutral location where his friend Bearmon brought Koji and Zoe after they ended up in his village. After the two sides argue what they learned, Bearmon and Kote lead them to a mural of Ornismon with Bokomon deeming the DigiCode to be incomplete. Their peaceful meeting is broken up as Kotemon and Bearmons older brothers Dinohyumon and Grizzlymon appear and battle each other. But after Takuya and Koji spirit evolve to Agunimon and KendoGarurumon to stop them, Dinohyumon and Grizzlymon take their respective brothers with them.
As the human Digimon prepare for battle after their leader dArcmon rallies the crowd, Takuya accepts Dinohyumons recruitment offer to allow Tommy to escape with Kotemon. A similar event with J.P. and Zoe spiriting Bearmon occurs at the beast Digimon village as Koji accepts Grizzlymons offer to fight during a speech by the beast Digimons leader Hippogriffomon. Zoe, Tommy, J.P, Bokomon, and Neemon help Bearmon, Kotemon, and many Fresh Digimon assemble the writing under the mural. But upon its completion, Bokomon finds that Ornismon is actually an evil Digimon that oppressed the island before being defeated by The Anicent Warriors AncientGreymon and AncientGarurumon. Furthermore, after the group notices a missing piece in the mural that is in the same shape as the ornament both dArcmon and Hippogriffomon possess, J.P. and Zoe proceed to find Takuya and Koji while Tommy, Bokomon, and Neemon stay to finish the mural of AncientGreymon and AncientGarurumon in hopes that they can find an answer to the crisis.
At the battlefield, Takuya and Koji eventually spirit evolve to BurningGreymon and Lobomon to stop the fight but end up getting both sides to turn on them before Kazemon and Beetlemon arrive. The two revealed that on their way to their friends, they discovered a horrible secret: the two armies leader being the same Digimon after accidentally catching dArcmon turning into Hippogriffomon. Exposed while forced to become dArcmon again, the fraud reveals to have been collecting the Fractal Code to revive and control Ornismon while assuming his true form: Murmukusmon. Overpowering the Legendary Warriors, Murmukusmon guides Ornismon to the murals of AncientGreymon and AncientGarurumon, which begin shining. Kotemon gives his life to protect them, and Bearmons tears along with Kotemons sacrifice summons spectral forms of the Ancient Warriors. Their appearance gives the DigiDestined a second wind with the island residents joining them as Agunimon takes out Murmukusmon before the Legendary Warriors destroy Ornismon. With Ornismon no more, the Lost Island returns to the Digital World with the two sides finally making peace with Kotemon turning up alive as he and Bearmon have a tearful reunion.
