Do-ah, a married woman, works at a massage parlor in the shady back alleys of Cheonho-dong. One day, a customer named Myeong-hoon comes in, looking for something more than a regular massage. While Do-ah is still learning the ropes, she accidentally touches Myeong-hoon in a sensitive area. This excites him, and he asks for more intimate services. Though Do-ah is disgusted, she reluctantly agrees to fulfill his desires.
