Summer paradise (1977)

Conventions of civility among family members are severely strained by the very real breakup of the bonds between them. During a few days at a vacation home, Katha, a woman in late middle age, tries to cope with an influx of discontented, disconnected relatives. Her divorced daughter brings all sorts of people to the house, including a woman-friend accompanied by her psychotic son; the grandfather of the house is convinced he is dying and is satisfied by nothing; and some friends drop off their angry teenage son to stay with her, while they go on a long trip abroad. Her friend Emma doesn't help much with keeping a lid on things, as she is a social worker who is fascinated by the awfulness of these situations.
