Hoshina Hikaru and three fellow Star Twinkle Precures are gazing at the stars when space suddenly warps around them, carrying them to the Miracle Planet, where the Miracle Lights are produced. An accident there has unleashed a darkness that swallows planets and stars, wiping out every Miracle Light except one, held by a factory worker named Piton. Piton uses it to call the Star Twinkle, Hugtto and Kirakira A La Mode Precures to his side. Pursued by the factory's police, the combined teams must work out who is responsible for the darkness before the universe loses its light. The film is a magical girl action fantasy.
