The episode begins with an Agumon escaping through an obscure sewer tunnel followed by an alarm going off at the DATS HQ. A female DATS agent is sent to investigate. Suddenly she sees lots of people who lie wounded on the ground, sealed off by police.

Cockatrimon goes on rampage, injuring Agumon. This made Masaru extremely angry and turned his anger against Cockatrimon. After successfully dodging all of Cockatrimon's attacks, Masaru striked it and received an instant burst of Digisoul. An old man emerged from the distance and threw an orange Digivice iC to him and explained how he can use the Digisoul to make Agumon evolve. Agumon evolved into Geo Greymon and finished off Cockatrimon with its Mega Flame attack, reverting it into a DigiTama.
