In her past life, Serena Jennings was force-fed poisonous snails by her husband, Ian Clark, and died. Reborn, she watches her mother-in-law and husband's family eat, sell, and give away apple snails, leading to their poisoning. Her sister-in-law dies, mother-in-law is arrested, and Ian Clark has a mental breakdown. Serena divorces, reclaims her dowry, and starts a new life.
