Blending stop-motion animation and silent film, a new narrative unfolds. The story follows a stubborn "tooth mouse" who clings to the past, and a restless "shark girl" who only chase the future. Their paths collide in a fierce, ritualistic battle on an altar. Can the mouse accept change while protecting what's dear? Can the shark acknowledge the weight of memory while relentlessly pursuing the future? This confrontation will ultimately lead them toward a "fatal growth", where both must destroy their old selves to be reborn.
