In a twisted jungle overrun by mutant vegetation, the Science Ninja Team faces their worst betrayal yet — the Blackbirds, once their trainees, now their enemies. Arrogant and armed with the latest tech, the Blackbirds dominate early, but the Science Ninja Team fights back with something stronger: experience, loyalty, and heart. With a surprise assist from the mysterious Raven, the Blackbirds are forced to retreat — but the emotional scars of betrayal linger, even in victory.
