Plazac is a commune in the Dordogne department in Aquitaine in southwestern France.

There are at least 20 nationalities represented among the villagers, and there is a lively social scene. A typical dinner will last for at least five hours and draw heavily on the products from the nearby Bordeaux wine region, as well as the local game, truffles, cepes (wild mushrooms) and foie gras. Plazacians, if there is such a word, believe that duck fat is the safest possible cooking oil, and is in fact very good for your cholesterol. Everyone seems to be living to a ripe old age, so it may well be true.
