==Synopsis==
Learning that is enslaved, Tai joins the DigiDestined's team to get back his partner. After a long day at school, the children immediately run to the computer lab, eager to get going. They are about to leave, but notice Yolei isn't there. They soon find her outside the door, and she is in a pretty down mood. They assure her that if her heart's not into it, she doesn't have to go with the rest of the group on the mission. They quickly enter the Digital World and find who, after looking around for a bit, informs the group that Agumon is being held in Rail Town.
Rail Town is where Ken is, who is meanwhile doing research and realizes that the Dark Rings aren't strong enough to control Ultimate level Digimon. He creates the Dark Spiral which is three times stronger than the rings and does many painful tests on . doesn't like to see Agumon suffer, so he sets him free, that way Ken could use him instead. Just as Ken has reached a solution to his problems, he realizes his captive is gone. He is furious with Wormmon and refuses to use a weak Digimon like him for his experiments. He notices the DigiDestined nearby and decides to go recapture his test subject.
While heading to the town, the DigiDestined run into a Woodmon who destroys a Control Spire and point the team in the right direction. When they arrive at the destination, they decide to split up to look for the missing Digimon. Agumon arrives on a train after escaping the Digimon Emperor's base and meets up with Tai and the others. Their reunion is cut short when the Emperor appears and recaptures Agumon with a Dark Spiral. Ken calls forth a squad of DarkTyrannomon and , , , and digivolve to fight them off. Ken then makes Agumon dark digivolve in to . Pleased to see the Dark Spiral is doing his job, Ken orders MetalGreymon to destroy the DigiDestined. Tai does his best to try to speak to Agumon, even though he's under evil control. MetalGreymon easily defeats the DigiDestined and leaves with his master.
Meanwhile, Yolei decides that she wants to get in on the action and enters the Digital World herself. She brings Matt with her, and they arrive just in time, as it appears Tai is acting rather depressed. He starts blaming himself for the situation, so Matt punches him in the face to knock sense into him, and Davis tries to calm them down. Ruefully, the team decides that the only thing they can do is defeat Agumon, so they set off after the Digimon Emperor.
