In a society that despises witches, Yeongeun lives in hiding, wondering through a bleak and monotonous life. Yet, she holds onto one final wish—to undo the twisted creation of her only daughter, Roo, a plant-like monster born of her distorted desires. But Roo yearns for a different destiny. Neither a witch nor a monster, she wishes to become a tree. She pleads with Yeongeun to find a new land where she can plant herself and finally take root.
