A girl named Ira is eleven years old and loves to read books about sorcery, but she is very angry that boys are always the main characters in all these books. To prove that girls can be great witches too, she decides to open a summer school of sorcery in the basement of her house. A select team enrolls in the school of sorcery: Irina's friends and neighbors, parents, Gusta's brother called Whiny and the dog Flea Bag.
