The atmosphere is gloomy at Falkenstein castle. Amid busy preparations for a festive costume ball, there is a burglary. And the miscreants have not only made off with valuable paintings, but – far worse – Count Falko's entire collection of monocles is gone. As if that weren't bad enough, the mood at neighboring Martinshof holiday farm is equally glum – not a single guest has booked in yet. Bibi and Tina need to come up with a plan to promote the farm, and that includes a bit of showy sprucking. To top it all off, Bibi has her first serious crush. Of course, it would have to be on Tarik, who – along with his four chaotic brothers and sisters – is turning Martinshof upside down ... while guarding a dark secret.
