Portrait artist Annie Somerville is living a happy life in the English country with her husband David and teenage children Sam and Gina. She just received a new commission, and her biggest worry is whether or not her mother-in-law is visiting for Easter.Then she receives a letter from France telling her that her childhood friend Julia has died, leaving Annie a box which she must come to Toulouse to fetch. Memories come flooding back of their summers spent vacationing with Julia's family: her mother Judith and young brothers Tim and Georgie.Upon her return from Toulouse, Annie is troubled. She can't seem to get her paintings to go the way she wants, she is avoiding her agent, David has been called away on business, and more and more troubling memories are overwhelming her as she sorts through the letters, photos and memorabilia in the box. What exactly is it that Annie fought so hard to forget about that last summer? Why did Julia disappear from Annie's life 30 years ago? And what will happen to Annie if she remembers?
