'M' is an elderly woman who drifts through life, a solitary figure navigating her familiar surroundings. Her days are filled with reflections on her memories, until she stumbles upon an ant that resembles her own existence. M chooses to invite this small creature into her world, filled with bittersweet recollections and an unsettling shadow. This unusual companionship continues until the arrival of a "mechanical angel," who comes to offer her assistance and perhaps a new beginning.
