America's top teen detectives team up to defuse a bombshell murder case. Nancy is in Seattle to join a whale-saving campaign. When a major fund-raiser is accused of murder, Nancy begins her own investigation. The Hardy brothers arrive in Seattle at the request of a fireworks manufacturer preparing the city's Fourth of July exhibition--a saboteur has targeted the stage for an Independence Day disaster. The fireworks are just beginning.
