A mysterious cosmic entity has plucked heroes, villains, and allies from different points in time and sealed them inside an enormous theater beyond space and reality. With no way to escape, the group—including Team Voltron, Princess Allura, Coran, and the Galaxy Garrison cadets—must watch visions from alternate universes, possible futures, forgotten histories, fan-made timelines, and "what if" scenarios. Time outside the room is frozen, meaning no one can alter their own timeline until the viewing is complete. Every reaction, argument, laugh, and emotional revelation is recorded by the theater itself, forcing enemies and friends alike to confront truths they'd never willingly face.
