The remaining human population fights for survival against a merciless army of robotic creatures. As tensions rise and hope dwindles, a small group of rebels takes on the fight to save humanity from complete annihilation.

In a future where robots have taken over the world, a group of soldiers led by a brave captain fight against the transforming robots in an epic battle to save humanity. The soldiers encounter various challenges, including a powerful android general and the threat of a fictional war. Along the way, they also grapple with issues of lesbianism and female-female relationships. Will they be able to defeat the robots and restore peace to the world?

20 years after the events of Transmorphers, a newer, more advanced species of alien robot descends on a rebuilt Earth, threatening once again to destroy the planet.
