Called in by a baffled Scotland Yard to track down an international smuggling ring which is bringing in drugs by air, the firm of Skyways Investigation Limited, led by former ace fighter-pilot Hunter Hawk, is soon hot on the trail. A suspicious move made by one of the crooks leads Hunter Hawk and his young cousin, redheaded Mike, to Geneva, where their exciting chase begins.
