Fifth Digimon Adventure tri film.

Pandy and Retro awaken naked on Earth with no recollection of their past. They embark on a devastating crime spree in search of food, clothing and transportation, but are captured by authorities and sent to the infamous lunar penitentiary named Dead Leaves. While incarcerated, they quickly discover that Dead Leaves is also a top-secret cloning facility, occupied by villainous guards and deformed genetic experiments. Ultra-manic chaos and hyper-violent bedlam ensue as they organize a prison break with the aid of their fellow mutant inmates.

When a gigantic, unearthly monster suddenly looms on the skyline of a Japanese city, the expected occurs—the Japan Self-Defense Forces roll out the tanks while the public panics. Nobody knows what it is or where it came from, but Yuki, a bold and inquisitive teenage girl, has a secret but might be a useful clue. Her friend Tetsu has been clandestinely caring for a bizarre creature called Cenco, which will soon prove itself to have some remarkable, even impossible characteristics. Another teenage boy, a stranger with some mysterious link to the monstrosity attacking the city, shows up, and his unwelcome interest in Tetsu's pet snuffs out any doubt of a connection—and lights the fuse for the coming battle.
