Ranger, the time-traveling golden retriever, has landed in Viking age Iceland, where he meets a girl named Helga, who seems perfectly able to take care of herself--until an erupting volcano and an early arriving baby forces Ranger and Helga to journey through the ash and smoke to find her father and bring him home.
