Mu Chen and her sister-in-law partner to run a restaurant, agreeing to split profits evenly. With the annual store profit reaching one million, the other party only gave her thirty thousand, and she was also verbally mocked by her husband's family. Heartbroken, she uses funds raised by her parents selling their property to open a new shop. The original store loses its head chef and its business collapses; the sister-in-law misuses inferior ingredients to host a banquet, causing an accident and saddening her with huge debts. The family repeatedly comes over to make trouble, spread rumors, and smear her. Mu Chen relies on complete procedures and evidence to protect her rights, successfully divorcing. In the end, Mu Chen's catering business grows larger and larger, while her sister-in-law's family falls into poverty and ruin.
