"Star Driver the Movie" condenses the narrative of the original "Star Driver" anime series into a feature-length film, retaining the core elements of its story and characters. The plot is set on the isolated Southern Cross Isle, where a mysterious organization known as the Glittering Crux operates in secrecy. The group seeks to awaken and control powerful entities called Cybodies, which are giant mecha-like beings that can only be activated within a hidden dimension known as Zero Time. The Cybodies are sealed within four Shrine Maidens, who are key to unlocking their full potential.

The protagonist, Takuto Tsunashi, arrives on the island and becomes embroiled in the conflict when he discovers his own connection to the Cybodies. Takuto is revealed to be the Galactic Pretty Boy, a legendary warrior who pilots the Tauburn, a unique Cybody that can operate outside Zero Time. As Takuto battles the Glittering Crux, he forms alliances with Sugata Shindō, the stoic heir to the Shindō family, and Wako Agemaki, one of the Shrine Maidens. Together, they strive to protect the island and prevent the Glittering Crux from achieving their goal of breaking the seals and unleashing the Cybodies' full power.

The film explores themes of identity, destiny, and the struggle between tradition and progress. Takuto's journey is marked by his growth as a pilot and his relationships with Sugata and Wako, which are tested by the escalating conflict. The Glittering Crux, led by the enigmatic Head, employs various strategies to achieve their aims, including manipulating the Shrine Maidens and challenging Takuto in high-stakes battles. The narrative builds toward a climactic confrontation, where the true nature of the Cybodies and the island's secrets are revealed, culminating in a resolution that ties together the fates of the main characters and the island itself.
