In the winter of 1982, Shen He is reborn in front of the memorial hall where her father lies in state after dying in the line of duty. In her previous life, her second uncle, Shen Changgui, pressed the dead man's finger onto a forged fingerprint and stole a secure state-owned job at the Third Cotton Mill for his daughter, Shen Lan. He then sold Shen He to a butcher for a bride price of 600 yuan, and she was tortured to death.
Reborn into this life, Shen He becomes a bloodthirsty avenger. She grabs an iron spike and nails the butcher's right hand to the spot, then threatens Shen Changgui with a knife until he returns the money and writes a document severing their family ties! Next, she storms into the factory office in bloodstained clothes and uses details about rigor mortis to stop the fraudulent claim to her job allocation. Then, with her astonishing talent for "repairing machines blindfolded," she turns the tables and earns a special promotion to Grade Four Technician.
But this is only the beginning of her revenge. Following the clues, Shen He catches her second aunt, Liu Guixiang, red-handed poisoning someone, and uncovers the crimes of the staff cafeteria's grain-trafficking operation. She also seizes a top-secret microfilm hidden inside imported machinery. It turns out that her second uncle has joined forces with a corrupt deputy factory director and a fake foreign businessman, hoping to empty the nation's strategic grain reserve of thousands of tons! Facing powerful protectors and attacks from hired killers, Shen He uses her ironclad evidence to set one deadly trap after another. She swears to make these bloodsucking wolves pay for their crimes in blood!
