After Sara Swerdlow's death in a nightly car accident, her excessively self-righteous mother Natalie shamelessly invites herself to move into her room at the remote summer house where her friends are on holiday as often before. Gay playwright Adam fails to evict her because of happily married Peter's cavalier hospitality. Soon everyone suffers facing Sara's, and their own past and present, as Nathalie only thought she really knew her 'all-confiding' daughter, which shifts several reports.
