In the 1990s, a car full of prisoners collides head-on with a large tractor rushing on the Panshan Highway. Injured prisoners struggle to get out of the overturned car. Prison police Yue Bing (Zhu Shunliang) and Liu Zhicheng (Fu Hengzhi), who were escorting the car, were also seriously injured, and severely warned the prisoners who wanted to take the opportunity to escape.
