Z for Zachariah

Nuclear-apocalypse survivor Ann Burden lives an agrarian life on her family's valley farmstead, sheltered from radioactive contaminants by rocky hillsides, favorable weather patterns, and an abundant ground-fed water supply. One day, Ann encounters refugee John Loomis. He claims to be an engineer, who, aided by medicines and a radiation suit, walked from a distant government bunker to Ann's valley. Loomis bathes in contaminated water, and immediately sickens, but is nursed back to health by Ann, who welcomes him into her farmhouse.
