The England cricket team is playing Australia in the second Ashes Test Match at 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 spectator's, scavenging what they need. One night all this changes when a combination of events threaten their way of life and their home.
