Grace Keslar, a wealthy eccentric widow living near Spicetown, Ohio, has opened a new business and invited customers to stay in her large home while they visit Spicetown. Her crazy-whiskered gray cat, Chauncey, (who may or may not be her late husband reincarnated) has done his part to interfere with the preparations and discourage the lodging arrangement. Now as guests begin to arrive, all he can do is try to police the environment, alert the other household members to any wrongdoing detected, and find someone he can collaborate with while ridding the mansion of evil!
