Digimon: Dark Worlds

Why are Digimon appearing and attacking the Human World? a group of kids, who soon become partner to their own Digimon ask that question also. The more they fight the evil Digimon, the more trouble they soon realize they're in. A very powerful evil Digimon that is capable of destroying both worlds is soon to be awakened. Can they stop this Digimon, and save both worlds?
