Mint is a little girl who is also the princess of the world of dreams and magic. Her world's natural nature reflects the hopes and ambitions of the people on Earth. It is now in jeopardy as individuals lose trust in their dreams and allow evil to infiltrate their hearts. Mint's world's ecosystem is beginning to wither and perish. On her 12th birthday, after a gala celebration with her father the King and her mother, she agrees to go to the world of humans to try to preserve people's hopes and dreams, and to prove that she has the qualities necessary to be a wise ruler. Her father arranges for her to reside with his sister, Mint's aunt Herb, who manages the family business.
