Synopsis
Lan and his friends are camping in Okuden Valley, with nature loving Sal acting as their chaperone, when Sal runs into an old childhood friend: Dave, now a park ranger, who quickly makes friends with Lan and the gang as well. But unknown to our friends, Dave has a dark secret: he also works for the criminal organization called Grave. At night, Dave's NetNavi QuickMan sneaks into the net control system for Okuden Dam and moves to destroy it. Sal and Lan race to stop his plan and find that his intentions aren't what they seem. But when he starts to have a change of heart, a new NetNavi, CutMan, appears on the scene to finish the job and eliminate QuickMan.
