Women have become nothing more than property, and their value lies solely in their ability to bear children. In this new society, Shari, a young woman, finds herself in a desperate situation. Her little brother's life is in danger, and she must make a difficult decision to save him. She volunteers for a life at the Hucow Ranch, a place where women are transformed into livestock to be bred and milked. At the ranch, Shari, now known as Hucow 547, undergoes a series of physical and emotional transformations to prepare her for her new role. She is trained to accept the rigors of breeding and milking, and her body is altered to accommodate the needs of the ranch. Her first televised breeding is a success, and she is immediately requested again by the man who sent her to the ranch. However, things do not go as planned, and when it is discovered that Hucow 547 is not pregnant, she is sent to the Stocks, where the Bulls are.
