After a string of bad luck at the gambling table, Ngo decides to engage in a bout of "cat-planting," and unfortunately for Sau Yong, she accidentally witnesses the bloody, cruel "ritual." After this, Sau Yong's behavior takes a turn for the strange. "Corpse Aroma" tells the story of Yan (Jennifer Tse), a mortuary makeup artist who loves to meet new female friends. One day, she picks up a phone from the street and starts to engage in a text conversation with a mysterious girl. After a period of getting to know one another, the girl asks Yan to help her find something she's lost.
