Based on Frances Hodgson Burnett’s 1911 book, the story centers on Mary Lennox, a troubled, sickly, 10-year-old orphan who is sent to live with an uncle in England when her parents die in a cholera outbreak. Initially sour and rude, Mary begins to explore the grounds of her uncle’s estate and befriends a robin. After hearing of the eponymous walled garden, she sets out to find it, discovering it to be more magical than she ever could have imagined.
