Betty (Sonja Martin), living in Munich, is notified that she has inherited a "castle" in Spain. She begs her boyfriend to go to Spain with her to check it out. He, being both skeptical and busy with his studies, refuses. She goes anyway and finds that it really is a castle, "Casa del Flores." She discovers that it is being used as a kind of "Spanish no-tell motel" by the lawyer assigned to be the executor and his female accomplice. The executor pressures her to sell it and return to Munich but she wants to keep it as a "Castle for Lovers." Who will prevail?
