But when his wife Eva dies suddenly, Max discovers something troubling amongst her private possessions - an old compact with a very personal note from another man. To add to his grief, Max must grapple with the possibility that his 65-year marriage might have been built on a lie. In quest of peace, Max seeks out new meaning in what should be his tranquil autumn days and finds comfort from the friendships he develops with his fellow widowers. Just as he manages to get his life back on track, he finally learns the surprising truth about his wife and his life.
