In the early years of the Republic of China, Xi Yebai, the young commander of the Beiyang Governor-General, held an IOU ten years ago, on which was a huge sum of money pledged by the father of the famous actress Lan Jiyun. Now that the debt period was about to expire, he was given a choice: marry into the commander's house to pay off the debt, or pay off the principal with interest within three days; Lan Jiyun hated this manipulated marriage and worked hard to sing. Saving money, she found that the theater troupe was closed, the bank refused to pay, and every step was blocked by invisible hands; she dug out the secret letter among her father's belongings, and vaguely realized that there was a conspiracy to steal arms and frame up behind the IOU; She becomes more and more confused; the woman who secretly cut off her costume and bribed the gangsters to destroy the scene was actually Xi Yebai's cousin and fiancée candidate; after Lan Jiyun was forced to enter the house, he found old files in the study and discovered that his father was not a creditor but a scapegoat. The real culprit was a powerful elder in the governor's house; In order to protect her, Xi Yebai broke with the family and ceded military power, but was seriously injured in a plot; Lan Jiyun chose to stay at the critical moment of life and death, and investigated the evidence to bring down the mastermind; the ten-year loan agreement was eventually burned to ashes, and the two transformed from a twisted relationship between creditors and debtors into comrades and lovers who broke the old order side by side.
