Bibi and Tina, two cheerful, open-minded teenagers are inseparable friends and passionate horse-riders. Whenever she can, Bibi visits her friend at Martin’s Farm, where the two of them help Tina’s mother. Susanne Martin is not totally comfortable with Bibi’s witchcraft abilities, and Bibi is only allowed to use them in emergency situations. Bibi sometimes interprets the word „emergency“ rather loosely.
While Bibi is a little dare devil, Tina is more reserved. But she is easily motivated by Bibi, particularly when there is any injustice to put right. Tina’s friend, Alexander von Falkenstein, is generally there with them. Alex is the son of the Count Falko von Falkenstein, who owns the Martin’s Farm.
The adventurous girls love nature and are passionate about animals. They are at their happiest when riding and racing on their horses Sabrina and Amadeus.
