Robin and his friends spring into action when Prince John's guards try to take a man's ring, a family heirloom. During the chaos, Marian casts a spell which she thinks has turned the ring into a chicken. When she can't reverse the spell, she and Scarlett go off to find Derke to ask for his help. Events go horribly wrong when little Isabelle steals Marian's spell book and the gang must retrieve it before Marian loses her ability to cast spells forever.
