A day in the life of a young boy living in a country that routinely fires large cannons at an unknown enemy.

A trilogy of separate stories. In "Labyrinth labyrinthos", a girl and her cat enter a strange world. In "Running Man", a racer takes on the ultimate opponent. In "Construction Cancellation Order", a man must shut down worker robots.

Three back-to-back anime films by three different directors make up this sci-fi trilogy three years in the making.
