A fictional nail salon suddenly opened at an undisclosed location in Tokyo. By distributing flyers on the streets advertising free trial sessions, they lure customers into the shop and then guide them under the pretense of optional services. Using methods bordering on illegal, they exploit women's beauty consciousness to draw them into the lesbian world. Amateur women who get caught up in the free trial course inevitably become involved in hardcore lesbian play. The main feature includes real faces, faithfully recreating a genuine atmosphere.
