The school festival never starts. Every morning Ataru wakes up to the same day, the same chaos, the same exhausted scramble, and nobody remembers it happened before. What begins as slapstick comedy about a rushed festival slowly becomes something heavier, a quiet horror about being trapped in repetition, about the people you love becoming strangers because they'll never know you. The film trusts you to feel the weight before it explains the mechanics. By the time it does, you're not watching a time loop anymore. You're watching characters claw at the bars of a dream that doesn't want to let them wake up.

The night before Tomobiki High's festival, Class 2-4 scrambles through final preparations. Ataru, Lum, and their chaotic friends push through exhaustion to build props, sew costumes, and somehow get by on little sleep. When morning arrives, they're still not done. They'll finish tomorrow, they promise themselves. But tomorrow never quite arrives. The festival prep repeats. Then repeats again. Days blur together as the same preparations cycle endlessly, and the city around them falls silent, its buildings left to decay. The students begin to realize something is off. Doubt creeps in: are they trapped in a dream, or have they finally woken up? What begins as a comedy about school festival chaos turns into a challenge to what they believe about reality and dreams. The question becomes less about escaping and more about whether it matters, if they can spend every day having fun together.
