In a not-so-distant future, a group of actors who once portrayed the heroes of a successful science fiction television series finds themselves trapped in the routine of conventions and the nostalgic affection of fans. However, their lives take an unexpected turn when a real alien race, the Thermians, mistake their performances for an operations manual. Believing that these actors are true heroes, the Thermians seek their help to confront an alien tyrant bent on annihilating them.
With a varied cast that includes a charismatic captain, a temperamental first officer, a beautiful yet underestimated actress, and a nerdy video game player, the group must put aside their personal grudges and industry egos to become the heroes they once portrayed. As they embark on an epic intergalactic mission, they must learn to work together and harness their "acting skills" to save a planet in peril.
Amid tons of laughter, overflowing action moments, and nods to pop culture, these actors face their own fears and doubts while discovering that, despite the distance between fiction and reality, true heroism can arise from the most unexpected sources. The adventure turns into a heartfelt comedy, where friendship and bravery are the keys to triumphing in this hilarious battle against the evil of the universe.
