A look at modern-day life in China's capital centered on a ménage-a-quatre involving a young woman, her boss, her husband and her boss's wife.
Lin and Wang are a wealthy couple, approaching middle age in Beijing. They are childless, because she is infertile. He owns a foot-massage parlor. One afternoon he rapes one of his workers, Liu, who has nearly passed out from drinking alcohol with a friend. Part of the assault is witnessed by Liu's husband, An-Kun, a window washer. He's angry with the boss and with his wife, and attacks Lin's car furiously. He seeks compensation and tries to blackmail him. Lin's wife counsels him and joins in revenge. Then, Liu realizes she's pregnant and a set of emotional calculations ensues: Lin wants to buy the child, Wang agrees but she has conditions, An-Kun goes back and forth and barely contains his anger; Liu withdraws. The baby comes. Can anything be sorted out?—Wiki
Massage girl Pingguo (Fan Bingbing) lives in a cramped apartment with her bad-tempered window cleaner husband Kun (Tong Dawei), barely eking by on their miniscule pay. When Pingguo gets raped by her boss Lin (Tony Leung) one afternoon, Kun, who is washing the windows of the building, witnesses the act. The enraged Kun tries to get even first by (unsuccessfully) blackmailing Lin, then by sleeping with Lin's wife (Elaine Kam). The relationships get even more tangled when Pingguo discovers she's pregnant. With the paternity of the baby up in the air, Kun, who is eager for money, strikes a deal with Lin, who is eager for a son.
