David's once care-free marriage starts disintegrating after he and Jenny, his wife, have a baby with Down's syndrome. She stops communicating with him on any level and devotes all her time to the baby. But then David manages to persuade her to make friends with another lady, Jane, who also has a baby with Down's. However, he soon starts an affair with Jane and, after Jenny finds out about this, she dies, having seemingly committed suicide. This makes David feel extremely guilty but he gets back together with Jane, who starts her own business, and they finally get married. But David has medical problems of his own..... This family drama, set in modern-day Britain, is told mainly from David's perspective but is interspersed with comments from the two women in his life describing how they feel about the events as they unfold.
