This is a mystery story in which a young wife suffers a shocking incident in which she is raped by sweaty men, leading her to have a double life as a chaste married woman and a prostitute, and even commits cold-blooded murder in order to protect herself.
The wife is a chaste married woman by day. By night, she wears a short wig and puts a fake mole on her chin, and becomes a prostitute. At the end of the film, we find that the reason why she became like that is because she got raped while she was out with her husband one night. There's also a scene where she, along with a female friend, attends a masquerade party (not as a prostitute) and a masked man starts raping her in a private room. She gives in and starts enjoying it.
