A resourceful young aviator copes with a forced landing that strands her and a friend on a wild reservation, then turns detective when suspicious visitors and odd occurrences suggest foul play. She applies flying skills, practical invention, and steady courage to pursue clues, confront traps, and navigate subterranean dangers and hidden motives, gradually unmasking the conspiracy behind the case. The narrative moves through tense rescues, investigative episodes, and tests of nerve, blending action, deduction, and companionship into an episodic mystery-adventure.
