Malevil

Emmanuel Comte is a school headmaster turned rancher in the rural village of Malejac, France. He uses his unexpected inheritance from his late uncle to purchase the titular Malevil, an English castle from The Hundred Years War neighboring his uncle's ranch. Once a tourist attraction, Malevil was condemned after a visitor was killed by falling masonry. The old castle becomes Emmanuel's passion and he spends a sizable amount of time and money renovating the property until it's comfortably habitable and operational.

His childhood friends stop by on Easter Sunday, 1977 to discuss local politics turning in their favor and end up tasting wine in the castle cellars.

Meanwhile, World War III happens.

Now Emmanuel and his friends are picking up the pieces and trying to survive after a nuclear holocaust. They need food, supplies, women, and what's left of the world around them is growing desperate and aggressive. But they have one key advantage: a fortified stronghold that weathered the centuries and the Apocalypse.
