Judith Bellwood regularly teases Samantha "Sam" Byrd, a clumsy girl who's in the same grade level.
One day, Sam meets a mysterious woman named Clarissa and gives her directions. Clarissa offers Sam three wishes. Sam hurriedly wishes that she was the best basketball player on the school's team. However, during the next basketball game, Samantha learns that she hasn't improved. All of her teammates have gotten worse!
Judith and the other girls on the basketball team become sickly and weak. Judith blames the team's misfortune on Sam. Later, Judith even calls Sam a witch. Sam wishes Judith away. This wish inadvertently causes everyone except for herself and Clarissa to disappear. Sam wishes that everything would return to normal, but she wants Judith to think of her as great. This becomes troublesome when Judith begins following Sam everywhere and stalking her.
Clarissa offers Sam one extra wish. Sam wishes that Judith had met Clarissa instead of her. A little while later, Sam sees Judith talking to Clarissa. Judith shouts, "Byrd, why don’t you fly away!" Sam, feeling lighter than before, sees a worm. Sam eats the worm, flutters her wings, and gleefully flies away, unaware that there's anything wrong.
Judith is depicted similarly in the book and in the television adaptation. However, the end of the episode is drastically different. Rather than wishing that Samantha would fly away, Judith wishes to be admired by everyone. Clarissa grants this wish by turning Judith into a statue.
Judith is regularly mean to Samantha, but she is also graceful and athletic.
In the book, Judith has coppery-red, wavy, shoulder-length hair and green eyes. Samantha describes her as pretty and says that she is about 5 feet and 2 inches tall.
In the episode, Judith has blond hair and blue eyes.
