Finally, some rain! But today of all days, the social media influencers Fritzi and Mitzi spend their vacation at the Martin's farm. Bibi and Tina have to think quick to get a good review for the Martin's farm. On top of that, the young, mysterious entrepreneur Kim Win Win arrives at the Martin's farm to buy land, and Holger falls head over heels in love with her. Fritzi and Mitzi create some sensationalism by posting videos of Bibi doing witchcraft and kids suddenly storm onto the Martin's farm. But in the end the girls understand that posting without consent is not allowed. They join Bibi and Tina as they go to visit Alex, who is desperately looking for a new song. Together they perform a song at the station, which creates a lot of hype!
