On her birthday, a pregnant woman is lured into a dense forest by her husband and best friend, who push her into a Crocodile Pool. She barely escapes with her life, endures repeated attacks from wild beasts, survives by eating wild food, and finds a mobile phone only to have the signal cut off. The villains pretend to organize a search and rescue operation while secretly planning to kill her, and trick the female lead's mother into signing a death confirmation to seize her Inheritance. The husband's younger sister notices suspicious clues and investigates the truth. The female lead goes through difficult labor and gives birth in the wild forest, and is rescued by her sister-in-law at a critical moment. After learning the full conspiracy, the female lead becomes completely ruthless and decides to return for revenge alongside her sister-in-law.
