In a distant future, Man is long gone, but the mice and rats have evolved and developed their own modern societies, complete with commerce, transportation, education, family values, friendships, prejudices... and war. While an uneasy peace exists between the nations of Mousputa and Ratvaria, subversive forces are at work to make sure it doesn't last, forces willing to use the terrible weapons of ancient Man! It's up to Captain Tiny and two plucky young boys to seek out the conspirators and undermine their plot before Rodentkind follows Man into extinction!
