A strange story of adultery, jealousy, voyeurism and revenge is told in chapters by three of the characters involved in this ambitious drama from director Zhang Yibai. Momo (Lin Yuan) is a photographer who has a less-than-healthy obsession with the lives of other people, especially the folks who live in the apartment complex near her studio.
As she share a story with us, John Zheng (Hu Jun) is one of the tenants at the complex -- a successful businessman, John has a beautiful wife named Rose Feng (Carina Lau) and a child. However, while keeping tabs on John, Momo discovers he also has a mistress, Sharon Liang (Song Jia), who runs a nail salon.
As Momo tries to uncover more about John's dalliances, she gets to know Rose, and discovers she's long been unhappy with John. As Rose becomes the victim of a persistent vandal who dumps red paint on her car and her home, John takes over telling the story and explains how he and Sharon met and became lovers.
As the story returns to where it left off, Liu Fendou (Liao Fan), the doorman at the apartment block, becomes the new narrator as John and Rose's child is kidnapped and a murder throws the other characters into disarray. Curiosity Kills The Cat (aka Haoqi Haisi Mao) was written for the screen by Huo Xin, one of China's leading screenwriters.
