At a facility operating in a former hospital, amateur women who came for a part-time job interview are told about the work duties. The job involves receiving a 3000cc enema of a new experimental drug and walking approximately 500 meters outdoors. They are informed that if they experience any physical changes, the data will be used for further development of the drug. Lured by the high payment, the women agree, receive the liquid as instructed, and begin walking through the streets. Soon, unexpected developments await them.
