Seventies: The Doctor Wife Arrives, The Cold-Faced Tough Guy Spoils Her to Heaven

Su Tong, a battle-hardened military physician from the twenty-first century, dies on a peacekeeping battlefield only to awaken in the body of Wu Tong, a sixteen-year-old girl in 1970s rural China. The original Wu Tong was the eldest daughter of a cruel and greedy family, subjected to relentless abuse and forced labor. Her mother, Wang Guilan, and younger sister, Wu Dongling, viewed her as a commodity rather than a human being. After two betrothed men died under mysterious circumstances, Wu Tong was labeled an ill-omened woman. Desperate for a bride price of fifty yuan, her mother sold her to a nearly fifty-year-old widower. Before the transfer, Wang Guilan drugged Wu Tong with a concoction from a village doctor and hired two ruffians, Li Youshuan and Wang Lao Er, to assault her on the journey to ensure she would submit to her fate. When Wu Tong regained consciousness in an abandoned cowshed and realized the men's intentions, she smashed her head against a pillar in a suicide attempt. Su Tong, inhabiting the dying girl's body, wakes up moments before the ruffians plan to bury her, believing her dead. She fights back but is too weak to escape effectively. In the ensuing struggle, a kerosene lamp is knocked over, igniting the cowshed and creating chaos.

Meanwhile, a high-stakes police ambush is underway nearby. Captain Qin Yi, a top investigator from the provincial bureau, is leading a operation to capture Ma Liu and Zhang Kui, two fugitives wanted for kidnapping a child across three provinces. The fire from the cowshed disrupts the ambush, drawing the attention of the police. Su Tong flees into the darkness and stumbles into Qin Yi's hiding spot. The fugitives, Ma Liu and Zhang Kui, also encounter her. Ma Liu, suffering from a severe illness and an arm wound from the earlier firefight, grabs Su Tong as a human shield. The police close in, but Ma Liu reveals he is wearing a homemade explosive vest attached to the kidnapped child, Dongdong. He demands a car, money, and supplies, threatening to detonate the device if his demands are not met. The police are forced to comply, providing a jeep for his escape.

During the getaway, Su Tong assesses the situation. She notices the child is in critical condition due to neglect and illness, and she recognizes that Ma Liu is physically deteriorating. Realizing she is the only one with the medical and combat expertise to intervene, Su Tong makes a decisive move. She offers to take the child's place as a hostage, a sacrifice that confuses both the police and the criminals. Ma Liu, suspicious but desperate, accepts the exchange and kicks the child out of the moving vehicle. Once alone in the jeep with the two fugitives, Su Tong seizes the opportunity. She exploits the rough terrain and Ma Liu's failing health to her advantage. She disarms Ma Liu of his explosive device, neutralizes Zhang Kui, and brings the jeep to a controlled crash in a farmland ditch. Using professional military binding techniques and bomb disposal knowledge, she secures both criminals and hides the evidence. She then waits for the pursuing police to arrive, feigning unconsciousness to avoid exposure.

Qin Yi discovers the scene and is stunned by the professional-grade bindings and the defused bomb. He suspects a trained operative was involved but finds no one else at the scene. Su Tong is taken to the hospital, where she recovers from her injuries and the lingering effects of the poison. Her heroic act of swapping places with the child becomes local news, brought to light by the talkative militia captain Ma Daming and Police Director Jiang Pinglu. They intend to publicize her bravery and secure a reward for her family. However, Su Tong's family arrives at the hospital not to care for her, but to claim the reward money and continue their abuse. Wang Guilan and Wu Dongling confront Su Tong, attempting to extort money from Qin Yi. Su Tong, no longer the submissive girl, calmly outlines the legal crimes committed against her, including attempted rape, illegal trafficking, and assault. She threatens to report them to the police, shocking her family and the officials present. Qin Yi, intrigued by her composure and hidden capabilities, begins to investigate her true identity, sensing that the frail village girl is far more than she appears.
