The Summer People(1974)

Two retirees decide to extend their vacation beyond the usual date, near a lake where they own a villa. From that moment on, everything becomes hostile: the butcher stops delivering meat, there is no milk, their electricity is cut off, and their car is sabotaged. Don't we want to show them that when your time is up, on vacation or in life, it's not a good idea to linger and that you have to disappear?
