Nuts in May (1976) - Mike Leigh
Their Morris packed to the gills, the punctilious Keith and the more spontaneous Candice-Marie arrive at a Dorset campground where they pay £10 in advance for ten nights. It's peaceful: they visit Corfe Castle, eat vegetarian food, and go in search of raw milk. Then a fellow with a loud radio pitches his tent near theirs: Keith is beside himself and it doesn't help when Candice-Marie decides to befriend the young man. Things get worse when a couple arrive on a motorcycle, make noisy love in their tent, and then start an illegal campfire. It's too much for Keith: he loses it. Will our middle-class couple find a bucolic corner, or are they doomed to brawl with the noisy and unwashed?
