Lucy, a pampered young Golden Retriever, is stolen by ruthless smugglers from her home in rural England and taken to a grim London kennel. A bold escape with her fellow canine inmates--a weepy but learned Spaniel, two stalwart Dobermans, a vain Afghan, and an ingenious Yorkshire Terrier, takes the friends through the unimagined perils of London. Whether it is something as simple as crossing busy streets or having to unearth long-dormant bravery to escape from a vicious gang of rats in the pitch-black London Underground, the often terrified friends must at all costs avoid recapture and certain return to their grim prison. Only by working as a cohesive team, can the dogs stay safe and find their way home.
