The England cricket team is playing Australia in the Second Ashes Test Match at Lord's, the World's most famous cricket ground. At one end of the ground stands the pavilion. For over a hundred years, it has played host to some of the greatest names in the game. However, within its walls and beneath its floors live a collection of less celebrated cricketers and their families. Compo, Don, Gubby, CMJ, Mrs. Heyhoe, and others are members of the pavilion's mouse colony. They live happily side by side with the visiting spectators, scavenging what they need. All this changes one night, when a combination of events threaten their way of life and their home.
