Moser and his team investigate the kidnapping of three old ladies and everyone seems to know more than them.

A body is discovered in the park surrounding Schönbrunn Palace - a young lady wearing only a fur coat and lingerie on a frigid Vienna day. As they investigate, Stocki questions a witness who indicates the groundskeeper. But despite his criminal record, Richard remains unconvinced and enlists Rex's help to investigate a local gynecologist with ties to the dead woman.
