Amuro Ray doesn't want to be a hero, he's a kid forced into a mobile suit because he's the only one who can pilot it, and that resentment never leaves him even as he wins. The Zeon soldiers aren't faceless enemies; they're people with names, families, and reasons that make sense from inside their cockpits. The movie compresses a year of war into two hours and sometimes that shows, but what lands is the weight of a conflict where nobody gets to go home unchanged.

The year is Universal Century 0079. Humanity has spread into space, living in huge cylindrical colonies grouped into clusters called Sides. One of them, Side 3, has declared itself the Principality of Zeon and gone to war with the Earth Federation, and after eight months neither side can break the stalemate. Zeon has held the advantage through its giant humanoid robots, known as mobile suits. Its ace pilot is Char Aznable, a masked man called the Red Comet. The Federation answers with the White Base and a prototype mobile suit of its own, the Gundam, developed at the colony Side 7. When Char's squadron finds the project and attacks, Amuro Ray, son of the Gundam's developer, climbs into the machine and drives the attackers back. Soon caught in direct conflict with Char, Amuro has to flee the colony aboard a Federation ship. The film is a mecha war drama with plenty of action and adventure.
