A group of spirited young women and a chaperon travel to the Adirondacks for summer camp and social diversions; their outing blends light-hearted social scenes, outdoor camping, boating and a masquerade with a mystery centered on a missing emerald and a deserted bungalow on a lake. Episodes include mishaps—overboard, a motor-boat chase, a night alone—and a tense search for a missing person, leading to unexpected help, finding, and recovery. The narrative balances friendship, resourcefulness, and suspense as the friends investigate clues, cope with dangers, and bring the situation to resolution.
