In a technologically advanced society, a group of women has adapted to a device that can stop their menstrual cycles. This device is part of a “liberation” that has taken place, allowing women personal sovereignty over their bodies and lifestyle choices. A middle-aged women's daughter, Perdita, decides to join a group called the Cyclists that counters the use of the device and embraces menstruation as part of their femininity. Perdita plans to have the device removed from her body and begin having her period again. The women in her family find themselves outraged by her decision. The grandmother arranges a family lunch with the intention of talking Perdita out of her decision. However, Perdita never arrives, and instead sends a representative from the Cyclists on her behalf. The representative attempts to explain the philosophy of the Cyclists to the family. She says that the patriarchy has conditioned women to believe that their periods are unnatural and having them removed is part of a master plan to ultimately control women’s bodies. In response to the representative's explanation, a discussion sparks amongst the restaurant table about the awful experiences the women had with their period before the “liberation” occurred. They begin sharing explicit details and joking about how painful their periods were. Perdita’s representative becomes so frustrated by how the family describes their periods that she storms off. The next day, Perdita calls her mother to announce that her representative told her all about the family lunch, and hearing all of their experiences made her change her mind about joining the Cyclists. Perdita asks her mother why she never told her there would be blood involved.
