In Paris, American sculptor Ross Marteau is renowned for his sensual depictions of women's bodies. After his latest love affair ends violently, he retreats to his home in Texas to start a new commission. In his local restaurant he meets Celeste, a charismatically beautiful woman, and she suggests another commission to him - her sister Leda. Intrigued he agrees to meet Leda and discovers that as well as being the most beautiful woman he has ever seen she is also the most grotesque, her body distorted by her being a hunchback.
Soon he is obsessively in love with Celeste and obsessively intrigued by Leda, and he finds himself pulled deeper and deeper into their world until someone close to them is killed, and Ross finds himself so deeply ensnared in their web of dark secrets and twisted motivations that he is close to mortal suffocation.
