The Girls from the Horse Farm 6 - T as in Thunderstorm

With Lilian still caring for her young foul, Alex borrows the farm’s horse Gilda, whenever she goes riding. One afternoon, Tine, Ina, and Alex take the horses to the ruins of a nearby castle. The girls get caught in a storm that spooks all the horses, but sends the skittish Gilda into a panic. When she manages to escape, they are sick with worry about the borrowed horse. After all, she is all alone, in unfamiliar surroundings, in the middle of a terrible thunderstorm.
