Police chief Ines insists Max and Miranda investigate the death of the dog of, and threatening letters deliver to, the island's most prestigious wine estate. It's owned by German Hans Weber, who disapproves of his son in law Rainer Schröder's expensive modernization and plans to move back to native Bavaria, expecting his daughter Yvonne to make her family follow as he's diagnosed with cancer, but that proves one of many fakes sold by a crook doctor. The detectives first concentrate on fired employee Federico Ramis and rival winery owner Emilio Byass, whose spinster daughter Margalida has a spicy affair, recalling the tragic one of her sibling and Rainer's heir, who drowned running away together.
