A woman gets killed in a department store. No one imagines this could lead to serial murders, but two days after the first murder, another homicide occurs. A woman is suffocated to death and the only evidence left at the crime scene is a sticker of the cartoon character “Princess Aurora”. A veteran detective OH suspects an attractive and lively woman named JUNG Soon-jung as the murderer. However, he does not tell anyone -not even his partner- that Jung also happens to be his ex-wife. Again and again, the Princess Aurora sticker is found… each with a dead body.
