The tried and true Romeo and Juliet scenario, this time with a young woman (Agnes Bruckner of THE WOODS) who is a werewolf and a young American artist who is visiting Romania. He first meets her in an old church, where he's researching information on werewolves - and continues to pursue her. He discovers that she works at her Aunt's chocolate shop and from that point on they are pretty much together.
However, she's been promised to the leader of the pack, the head werewolf, who takes a new bride every seven years and he doesn't like the idea that she's becoming familiar with a mere human. Once a month the clan of werewolves meet and hunt some unfortunate person they've chosen (usually a criminal), which bonds them together. It turns out that Romania is the last bastion of the Loup Garou, as they've been hunted to extinction in every other part of the world. In fact, the girl's parents were slain by humans when they had moved to America.
As far as werewolf movies go this falls somewhere in the middle. The coolest thing about BLOOD AND CHOCOLATE are the man to wolf transformations, which are simply beautiful. They don't go through a horrible, painful metamorphosis into an amalgamation of man and wolf - they magically transform into wolves with human intelligence.
