A rich man makes a deal with a magician to stop his daughter marrying, so that he can keep his fortune to himself. The magician gives him a pregnant horse to give to the girl for that purpose. When the girl is of mariageable age, the horse’s foal, now grown up, loses the girl in the forest and comes back home mad. Nobody knows where the girl is. A foundling boy who grows up with a woodsman and his wife in the forest, is given the power to rescue the girl by a gnome and a parrot whom he helps. In the event, he has to tame the mad horse, jump over a precipice, kill a dragon and fight the magician, all of which he succeeds, and is eventually able to rescue the girl.
