Mat is a young male rat that lives in a rat burrow in the abandoned wine cellar of an ample foursquare American house, together with other rats. He loves Nat, a small female mouse kept as a pet, who lives at the very top of said house. Being from different worlds, they plot a plan to escape to “the outside” together. His overconfidence puts them in peril’s way, incarnated by “The Claw”, a feral feline.
