This is a series that uses 10 hidden cameras to investigate what used to be popular sex shops are like today! The first one is "Ear Cleaning Salon". We sneak into a small shop that is now operating somewhere in Tokyo and set up a hidden camera. The footage shows that there are many men who try to get them to have sex in various ways. They lure them with money, talk, and sympathy. How will the girls at the salon, who are not allowed to have sex, respond to this situation?!
