A child's doll comes alive for one purpose: to discover what it means to exist before the light that created her burns out. Anpanman meets pure, unfiltered joy in her, the kind that doesn't need justification. Baikinman's envy, the same force that always breaks things, becomes the clock ticking against her life, turning a simple festival story into something that asks whether a few perfect days matter more than forever.
Anpanman discovers an inanimate doll lying abandoned and forgotten, only to witness something miraculous occur when a Star of Life descends from the sky to animate her. Dolly awakens to a world of wonder, and she throws herself into pure joy, convinced that laughter and play are all that matter. Her carefree philosophy spreads happiness wherever she goes, but darkness creeps in when her vital star begins to fade. Meanwhile, Baikinman nurses his own melancholy, remembering his creation through a lens of sorrow and loneliness. He channels these feelings into building a colossal machine, determined to remake the world according to his painful memories. What begins as a simple rescue mission transforms into something far larger: a collision between Dolly's unbridled optimism and Baikinman's desperate need to reshape his past. The Star Festival approaches as both forces converge, forcing Anpanman and his friends to defend not just one life, but the very meaning of existence itself. Friendship and purpose hang in the balance against despair and mechanical might.
