A woman is murdered in a department store. No one has any idea this is a serial killing, until two days later, a woman is found suffocated to death. The only evidence left at the crime scene is a sticker of the cartoon character ¡°Princess Aurora.¡± Veteran detective Oh suspects that an attractive woman named Jung Sun-jung is the killer. However, he doesn¡¯t tell anyone - not even his partner - that the suspect also happens to be his ex-wife. Again and again, the Princess Aurora sticker is found... each time with a dead body.
