I did not know at all this story, this TV movie. I just discover it now. The typical stuff that you could often have during the sixties and seventies. Now, it becomes rare. It evokes a countryside doctor - a scheme often evoked in TV series from this period - who has to deal with myths and legends, and one in particular. The action takes place, I guess, probably during the eighteenth century, and the production design of this TV movie shows with great accurracy how people lived in those remote villages of France during those periods. I know there was a remake, several years later, but I think another remake should be produced.
