It has been less than a year since Digimon returned for a special theatrical comeback, and the film series isn’t over yet. September will see the release of the fifth Digimon Adventure Tri. movie. The feature's first trailer has just been released, and the tense footage confirms the DigiDestined children have never faced a challenge as big as the one they do now.

The trailer, which can be seen above, focuses on Meicoomon and her partner Meiko. The younger girl is still recovering from an injury she received before her Digimon went berserk, and she isn’t sure whether she can be around her friend anymore. With Meicoomon locked up, Taichi and the original DigiDestined group try to show Meiko that her fate is inseparable from her partner now.

“We are not the chosen children,” the trailer explains. “We are the children chosen.”

As the footage goes on, fans get to see more of Meicoomon’s distorted power as she battles the virus locked with her. The rest of the real world also begins to undergo changes as the digital world becomes increasingly chaotic. The group of DigiDestined friends can only watch in horror as they stumble upon one realization: the two worlds are merging, and there is little they can do about it.
