Alice, a painter, has a baby for the sole purpose of observing it and painting experiences from it. She is unemotional and cares little for others, even for her sister, Rachel.
Rachel was born with an imbalanced body: her right hand like a flipper, her right foot a club foot. However, Rachel refuses to feel depressed by this, much to their mother's chagrin. Their mother, Margaret, resented Rachel and tried to keep her away from Alice. Rachel knows how Alice feels, yet loves Alice all the same.
