Du Di and Wu Cong Rui are resident doctors at the Obstetrics and Gynecology Department of one of China's top hospitals. The two friends originally had bright career prospects and stable relationships. However Du Di and Wu Cong Rui find themselves in direct competition.

Yang Fan lives in Yanjiao, which is separated from Beijing by the White River, during the quarantine. Her routine is pretty simple, cooking, cleaning and trying to abide by the rules. Her husband on the other hand, seems to be entangled in a voyeuristic/masturbatory web, where a classic painting of a woman hanging on the wall of her bedroom plays a crucial role. The two of them have sex, but things become more complicated when Yang Fan also starts sleeping with the enigmatic waiter of a restaurant she frequents, who has the tendency to pee under a tree every night after he closes shop. Instead of fighting, the three embark on a threesome trip that soon starts involving other people.
