Watch on SFlix. Countess von Drachenstein, owner of the traditional Drachenstein Castle Brewery, where the famous Drachenbräu beer has been brewed for 300 years, stubbornly refuses to agree to a merger between the Drachen and Sonnen breweries. Trude, the niece, and Fritz, the son of the manager of the Sonnenbrauerei, try in vain to poach Bachmeier, the master brewer at the Drachenbrauerei. But then Trude falls in love with Bachmeier, and Fritz with Countess Helene, the niece of the Countess von Drachenstein. And so the family businesses end up merging after all.
