In a tale of vampiric intrigue, Bathor, a vampire, transformed an entire village into his kind, staying just long enough to teach them survival skills before vowing to return in 2000 years after conquering the continent. However, the plan hits a snag as these immortal beings have a limited memory capacity. Over time, they forget their once-utopian society and, under the authoritarian rule of the fervent Grando, devolve into paranoid, superstitious fundamentalists. Their society fractures along racial and gender lines, targeting those they consider sinful. Amidst this chaos, long-separated lovers Élisabeth and Fantine, with the aid of previously exiled individuals, realize it is their destiny to reconstruct the past and safeguard what little remains before Bathor’s anticipated return.
