Your drill is the drill that will pierce the Heavens! In a far‑future world humanity has been forced to live underground for centuries, constantly threatened by tremors and cave‑ins. In one such tunnel village, shy Simon and his fearless friend Kamina share a dream: Kamina insists a surface world exists above them, and the two set out to find it, believing their drill can break through the sky.
