Because her father took on three hundred thousand in debt due to a business scam, Su Banxia was forced to marry into the Lin family to uncover the truth. She accidentally discovered that the heavily injured Lin family's eldest young master, Lin Qianzhou, had been secretly gathering evidence of his second uncle embezzling family property. One is proficient in accounts, while the other is skilled in plotting; the two go from unfamiliar spouses to fighting shoulder to shoulder, tracing fake accounts to uncover huge kickbacks and a conspiracy to seize property. Facing framing and threats, they insist on using evidence and the law to uphold justice, ultimately clearing her father's grievance, guarding the century-old sauce garden, paying back the workers' wages, and harvesting a sincere relationship and a brand-new life.
