A spirited young woman in a small town decides to welcome and assist returning soldiers, taking a particular interest in a stranded substitute whose awkward arrival leads to mystery and danger. She, her family, and friends investigate disappearances and suspicious visitors, pursue the missing man across country, and employ ruses, disguises, and daring escapes to uncover a plot of conspirators and rescue him. The narrative balances home-front loyalty and youthful initiative with adventure elements, depicting community responsibility, clever problem-solving, and moral courage amid postwar readjustment.
