On a hot June morning, Robert Riordan tells his wife Gretta that he is going to the nearest kiosk to get a newspaper. And he never comes back. Three adult children come to the aid of the inconsolable woman: sisters who have not spoken to each other for many years, and a brother who has practically lost faith in his own family happiness. Each of them has their own versions and guesses as to where their father could have gone. But no one even suspects that Gretta has carefully guarded a secret for many years that could put everything in its place.
