In a small closed village in China before the mid-1990s, human blood smuggling business was rampant, which was an endless source of income. At the same time, a large number of incurable "fever" spread because the blood selling organizers saved costs and shared needles with everyone. People who sell blood here are called "blood heads", and they always make money from the trade between life and darkness. Since the outbreak of fever (HIV) in this village, everything has changed. Some crazy mouths (kings) have been shouting with broken horns all day: "There is a new medicine for fever!" " The originally harmonious family members were also torn apart by the heat, and many people died.

There is a teacher in the village who is called "Old Zhu Zhu" (Tao Zeru). His eldest son, Zhao Quan (Pu Cunxin), is a famous leader in the village. Because of the prevalence of fever, some people think that it is a complete blood trade that brings disaster. Some villagers secretly poisoned Lao Zhuzhu's chicken, poisoned his dog, and poisoned his whole son Xiao Xin (Zetao Hu) with poisonous tomatoes. Old Zhu Zhu was still bent on doing something for the villagers, so he turned the abandoned Niangniangmiao Primary School into a concentration camp for patients to take care of each other, and old Zhu Zhu himself moved in at the same time. Zhao Deyi (Aaron Kwok), the second son of the old pig, was originally engaged in the so-called blood trading business with his brother, but he was also infected with fever. His wife, Yan Hao (Li Danyang), kept him at a distance, even afraid to hold his hand, and he moved into the school with the old pig. Qin Qin (Zhang Ziyi), the daughter-in-law of Xiao Hai (Cai Guoqing), the nephew of old Zhu Zhu, had to leave Xiao Hai and move into the school doctor's concentration camp because she wanted to buy a bottle of shampoo to sell blood. In a word, this is everyone's new home.

In this school concentration camp, everyone lives in the same room, eats a bowl of rice, and a seemingly harmonious life begins. Unexpectedly, a series of bizarre theft cases suddenly happened. First, the acting village chief Si Lun (Sun Shi) lost the official seal of the village, and then inexplicably lost the rice stolen by Jiang Shi, who was in charge of cooking for everyone, and even lost his cotton-padded jacket. After several twists and turns, I found the lost things one after another. People in villages and schools are still dying. When fanaticism spread to villages and took their lives, they also exposed deep-rooted bad habits, such as stealing, robbing money, fighting for power and profit, and being short-sighted. Ao and Qinqin gradually fell in love with each other because of the theft, and the other half had abandoned themselves, so they decided to be together. But this relationship is very bumpy and ethically unacceptable, and the villagers scoff at it. However, after many hardships, they finally divorced their original spouse and stayed together. Candies are sent from door to door, but they can't escape the death caused by fever behind their happiness. On the night of onset, Qinqin soaked her body in cold water to cool down. She didn't have a good fever, and it got worse. The next morning, when I woke up, I was still waving to Qinqin, but Qinqin had already left, and there was their marriage certificate at the bedside of Qinqin. Sad and proud, he cut his thigh with a sickle, and blood kept flowing out of the door.
