Shyama, a forty-eight-year-old London divorcée, already has an unruly teenage daughter, but that doesn't stop her and her younger lover, Toby, from wanting a child together. Their relationship may look like a cliché, but despite the news from her doctor that she no longer has any viable eggs, Shyama's not ready to give up on their dream of having a baby. So they decide to find an Indian surrogate to carry their child, which is how they meet Mala, a young woman trapped in an oppressive marriage in a small Indian town from which she's desperate to escape. But as the pregnancy progresses, they discover that their simple arrangement may be far more complicated than it seems.
