In the year 80 AMM (After Mickey Mouse) on the anthropomorphic animal-controlled Planet X, a party of mafioso cats plot to enact a genocide against the mouse population of the world. Mouse scientist Professor Fushimishi seems to have found the weapon against the threat to his people's lives and calls Intermouse, who then call its best (albeit retired) agent, Nick Grabowsky, to get the plans, and as a distraction, they send a second agent - Sergeant Lazy Dick - for the mission.
