The story tells the story of a little girl, Mary, who is eccentric and withdrawn. After her parents died, Lenox lived in her uncle's mysterious and gloomy house. A magical experience made Mary break into a long-term closed and barren garden. Mary, Dickon, a peasant boy, and Colin, a sick young master who has been locked in a dark room all the year round, found the key to happiness and experienced a poetic resurrection with the garden.
