Floyd Collins, exploring Sand Cave, uses the echoes of his voice to sound out the region, and falls through a tight passageway when his foot became trapped, wedged in position by a small rock. His family and his fellow cavers try to free him; when it becomes clear that his rescue will not be easy, his brother Homer spends the night in the cave with him. William Burke "Skeets" Miller, a small man, is able to squeeze through and visit with Floyd, relaying stories which were printed in the news.
