Flesh for Frankenstein Bande son (1973) BO

In Serbia, middle-aged Baron Frankenstein lives with the Baroness Katrin, his wife/sister and their two teenage children, Monica and Erik. He dreams of a super-race, returning Serbia to its grand connections to ancient Greece. In his laboratory, assisted by Otto, he builds a desirable female body, but needs a male who will be super-body and super-lover. He thinks he has found just the right brain to go with a body he's built, but he's made an error, taking the head of a asexual ascetic. Meanwhile, the Baroness has her lusts, and she fastens on Nicholas, farmhand boy and a friend of the dead lad. Can the Baron pull off his grand plan? He brings the two zombies together to mate. Meanwhile, Nicholas tries to free his dead friend. What about the Baron's children?
