"When Romy, a promising young artist in the male-dominated art scene of 1970s California, dies in suspicious circumstances, it is not long before her famous husband Billy finds a replacement. Paz, fresh out of art school in New York, returns to California and quickly marries Billy. But she is haunted by Romy, who is everywhere: in the photos and notebooks and art strewn around the house, and in the eyes of the baby she left behind, the baby Paz is now mother to. While Billy is away, strange things start to happen. Photographs move, noises reverberate through the house, people start to question what really happened the night Romy died. Then, a postcard arrives in Romy's handwriting. As Paz becomes increasingly obsessed by the woman she has replaced and the absent man she has married, a sinister truth begins to emerge, driving her deep into the desert to unearth well-kept secrets.
