Based on a play. A group assembles in the run-down country cottage owned by one couple. Their son's mousy would-be girlfriend takes on his glamorous 'latest', a haggard clothes horse with a ridiculous 40s hairdo. She asks her hostess if the family dresses for dinner. No, she says, because we don't have it. We have supper - something, and cheese and biscuits. As the mother goes out, the girlfriend mutters "cheese and biscuits". Sounds like nothing, but it's a very funny moment. Everyone is somewhat obsessed by food, but it was just post-war, and shortages and rationing ruled people's lives. No wonder Dad and friend Adrian go poaching salmon, which gives Adrian courage to propose to the lady he admires. Plus there's the ghastly village hall concert and antics of obnoxious rich party-goers. Everyone acts their socks off, including the wasps at the picnic. The salmon just has to play dead. By the way, it ends happily.
