In the winter of 1980, modern surgeon Su Wanqing transformed into the youngest daughter of the Su family who was forced by her family to marry as a substitute. On their wedding night, they faced Gu Zhanting, the "living king of hell" in a wheelchair - a retired military officer who was disabled due to war. He was violent and gloomy. His eight-year-old stepson Gu Nianjun smashed the briquettes and yelled at her: "Get out of here, you vixen who killed my mother!" The game of life and death in the Tongzi Tower: She used aspirin to save a dying child but was reported as a "suspected enemy agent". At the critical moment, Gu Zhanting's prosthetic leg oozed blood and he stood up with his military boots crushing the medicine bottle: "My daughter-in-law of the Gu family is not your turn to judge!"
When the spring tide of reform and opening up surged, Su Wanqing broke through the dilemma of fate: her renovation of military sewing machines was criticized, but she turned around and revitalized the whole village's orchards with a canned hawthorn formula; her creation of "Yongjun Brand" instant wontons attracted the siege of traditional factories. And the bloody legacy came quietly - Hong Kong businessman's widow Bai Fengyi recognized her relatives with a huge sum of money, and the secret of her betrayal was involved in the embezzlement of military pay; real estate tycoon Cheng Jiangnan forcibly demolished the military factory, and hundreds of old ladies in wheelchairs built a human wall to defend themselves. When the steel bar pierced Gu Nianjun's chest, Su Wanqing's battlefield first aid knife was sharp: "Burn the needle with white wine! Now!"
From the top-secret film hidden by the paralyzed husband's prosthetic limb to the coded paintings stolen by the Cheng family to resist U. S. Aggression and aid Korea, the couple worked together to tear apart the shady story of thirty years. On a rainy night in 1991, Cheng Jiangnan fell from a building and laughed wildly: "The gold on the ground has long been stained with human blood!" Su Wanqing held Gu Zhanting's hand tightly and looked at her stepson who was reborn as a military doctor. This road to Nirvana is finally forged into new life with blood and fire
