Three years ago, Situ Yi was kicked out of Hongxing Machinery Factory and saddled with the blame for falsifying data. He spent three years driving a taxi. Then a broken M8 bolt fell into his palm, and a golden label appeared before his eyes: Never loosens: self-locking design.
He takes over the bankrupt Yonggu Screw Factory, with seven veteran workers joining him. The wire rod from the scrap yard south of town is mixed with recycled steel, creditors are at the door threatening to dismantle the machines, and the person who falsified the data three years ago is waiting for him in the office of Hengli Precision.
The agricultural machinery order is due in four days. Five thousand screws: if even one loosens, it's all over. Cao the Fat wants to convert his debt into shares, and Su Man is holding adulterated materials to force him to give in. But the screw in his hand, once tightened, can't be removed by anyone.
