But while Emma and her husband Jonathan are on vacation at the Hamptons, a child drowns in the sea, and suspicion falls on Emma. As her picture-perfect life spirals out of control, and old wounds resurface, a persistent and monotonous voice in Emma’s head threatens to destroy all that she has worked for... Taut, elegant and mesmerising, Don’t Think a Single Thought lays bare a marriage, and a woman, and examines the decisions – and mistakes – which shape all of our lives.
