In a small, isolated town on the North Norfolk coast, Fran's life is unravelling.

As she fills her days cleaning the caravan park she owns, she is preoccupied by worry - about the behaviour of her son, the growing absence of her husband and the strained relationship with her sister. Her one source of solace is slipping out to the beach early in the morning, to watch the birds.

Small-town tension simmers when a new teacher starts at the local school and a Romany community settle in the field adjoining Fran's caravan park. From the distance of his caravan, seventy-year-old Tad quietly watches the townspeople - mainly, Fran's family.

When the schoolteacher and Fran's brother-in-law both go missing on the same night, accusations fly. Yet all Fran can seem to care about is the birds.
