Joan Crawford is a driven actress and compulsively clean housekeeper who tries controlling the lives of those around her as tightly as she controls herself. To prepare to work at MGM Studios, she rises at 4:00 a.m., scrubbing her face and arms with soap and boiling water before plunging her face into a bowl of witch hazel and ice to close the pores. When Helga, a new maid, thinks Joan's living room is spotless, Joan finds one minor detail she overlooked and loses her temper.
