Andy, a young and broken boy, finds himself trapped in a world made of paper and ink, surrounded by creatures made of ink, ruled by a vicious demon. He wishes to reunite and bring back his family. But, it's easier said than done. He must fight the world's greatest evils, and survive the horrors that lay beyond his safe haven.
