A married ad designer (Meguro) is having an affair with a married woman (Ming). When an ad agency head visits Meguro, it’s revealed that he’s Ming’s husband (Shanwei). Shanwei warns Meguro to not only continue the affair but also record (for Shanwei) and “mentor” Ming in a series of escalating sexual domination/humiliation rituals. If Meguro refuses, Shanwei will disclose the affair to everyone, including Meguro’s wife.
