Orris the rat lives alone in an old barn surrounded by his treasures, until the day his solitude is disrupted by a sudden flutter of wings and a loud screech. A small owl has gotten caught in a trap in the barn. Can Orris "make the good and noble choice" (as the king on his prized sardine can might recommend) and rescue the owl, despite the fact that owls and rats are natural enemies? And if he does, will he be ready for the consequences?
