Born in Shanghai, China, in 1936, Judy is an English pointer who finds her place on a English gunboat patrolling the Yangtze River, battling pirates, contending with the Japanese occupiers, and protecting her human shipmates--until they all end up in a Japanese prison camp in Sumatra at the beginning of World War II, where every day is a struggle to survive.

Based on the story of a real dog in World War II, and told from the dog's point of view.
