So Himewaka was a Digidestined that lost her Digimon and she wants to see it and that's why she's with the bad guys. They wanted the reset to happen so all the Digimon that were lost could come back since apparently if a Digimon is destroyed outside of the Digital World, it's gone for good. But the reset would restore them back.
After meeting up with their Digimon in their In-Training stages, the Digi-Destined and their Digimon just clicked together despite the Digimon's memory loss. Well all of them besides Yokomon and Sora. Even after Digivolving with the rest of them, Biyomon still didn't want anything to with Sora. They all got separated because of Meachinedramon's attack, but Sora managed to meet with Meiko who came to the Digital World somehow who met up with Meicoomon again.
T.K. seeing Elecmon again in the Digimon village was nice even if they couldn't remember each other.
The whole group managed to meet up again, but not before Gennai sent Machinedramon along with MetalSeadramon after them again.
The problem was their Digimon couldn't Digivolve until Tai and Matt got swept under the water by MetalSeadramon. To save them Agumon and Gabumon Digivolved to their Mega forms and beat MetalSeadramon just like before.
And it took some time, but Biyomon managed to accept Sora as her partner and having her risk her life for her let her Digivolve to Phoenixmon. (They probably decided to not use Hououmon because of the name similarity to a certain other fire bird.). But with help from HerculesKabuterimon and Seraphimon, (Which came out of nowhere, totally not earned at all. If anything that should have happened in the last movie.), they beat Machinedramon. But while they were doing that Gennai got to Meiko and Meicoomon.
In the next movie, Omnimon, Alphamon, Jesmon, (who made an appearance as Hackmon here which such a deep voice), and Meicoomon in a new form are going to fight, so that's going to be cool I hope. This movie was probably the one I like the least. I do not like the whole memory loss thing at all, it better be fixed by the end.
I really don't like what happened to Gennai, licking Sora like that was just gross. He was the one who helped them with everything before, so it's sad to see him like this. Who or whatever this King Drasil is, it has to go. Meicoomon is even more important than I thought.
