Mary Lennox, played by Kate Maberly, is a ten-year-old British girl residing in India at the turn of the 20th century. Neglected by her parents, portrayed by Irène Jacob and Colin Bruce, Mary is left under the care of an Aya, a native servant named Parsan Singh, while her parents revel in social gatherings and various entertainments. This sense of abandonment fosters a deep-seated anger within Mary, who displays a bitterness that belies her tender age. Rather than expressing her feelings through tears, her ire manifests in rebellious behavior. One fateful night, as her parents are away at a nearby soirée, Mary breaks her mother's cherished ivory elephant and hides the remnants beneath her parents' bed. Suddenly, the earth trembles with a violent earthquake, a harbinger of change, leading to chaos and destruction. Amidst the turmoil, Mary loses both of her parents, leaving her forsaken and alone.
Months later, Mary finds herself arriving by ship in Liverpool, England, where she is greeted by Maggie Smith, who plays the stern headkeeper of Misselthwaite Manor, Mrs. Medlock. The grand manor is owned by her somber uncle, John Lynch, Lord Archibald Craven. He is a grieving man, still mourning the loss of his wife, who happened to be Mary’s mother’s twin sister. Mrs. Medlock, understanding the delicate nature of the household, cautions Mary to avoid her uncle and seek amusement without causing trouble. Despite Mary’s disdain for the cold, gloomy atmosphere that envelops the manor in the chill of winter, she finds an unexpected ally in her kind-hearted servant, Laura Crossley, who portrays Martha. Martha is patient and nurturing, offering Mary a jump rope as a token of friendship and sharing stories of her brother, Andrew Knott, Dickon, who is around Mary's age.
As Mary begins to explore the intricacies of Misselthwaite Manor, she becomes aware of the secrets it harbors. Mysterious cries interrupt her nights, whispers of lost souls resonating through the halls, yet the servants remain tight-lipped about their origin. One evening, she stumbles upon a concealed door in her room leading to forgotten parts of the manor. Inside one dusty chamber—a previous sanctuary for her aunt—Mary discovers an ivory elephant reminiscent of her mother’s along with a key hidden in a drawer. Her adventures on the grounds introduce her to Walter Sparrow, an old gardener named Ben Weatherstaff, who recognizes echoes of the late mistress in Mary but warns her not to pry into the estate’s secrets. When she inquires about an overgrown garden shut away by a stone wall, he reveals it once belonged to Mrs. Craven, and has remained locked since her passing.
Determined, Mary finds a secret door hidden in the ivy-covered wall and with the key she discovered, opens the gate to the neglected garden. Here, she discovers a realm long-since forgotten, yet teeming with untapped potential. To her surprise, her uncle summons her one day, leading to her first encounter with him. Lord Craven, portrayed by John Lynch, is a broken man, burdened by memories of Mary’s mother and his dearly departed wife. Mary, filled with resolve, persuades him to allow her to remain at the manor, promising to cultivate a patch of earth, which piques his curiosity enough to permit it.
As spring blooms around them, Mary frequently revisits the garden, where she meets Dickon, an ardent nature lover. He reassures her that the plants are merely in slumber, awaiting the right time to awaken. Together, they begin restoring the garden back to life, revealing a world of magic and growth. A swing hanging from a tree reminds them of a tragic past where Mrs. Craven had met her fate.
One particularly poignant night, haunted by dreams of her mother, Mary follows the sound of crying to discover a mysterious boy, Colin Craven, played by Heydon Prowse. He reveals his identity as her cousin, isolated and bedridden due to a perceived affliction. Sharing their world of grief, the children bond, and Mary’s spirit encourages Colin to explore beyond the confines of his room. Defying Medlock’s strict oversight, the two form a secret alliance, albeit with constant challenges, including Colin’s moments of despair as he struggles with his self-esteem and health.
Mary’s determination inspires Colin, leading her to open the windows inviting sunlight into his dreary world. One day, filled with hope and the promise of adventure, Colin joins Mary and Dickon outside, where he finds not only the garden but also a new lease on life. The children pledge to keep his newfound strength a secret, hoping to astonish Lord Craven upon his return. Medlock, viewing Mary as a threat to Colin’s fragile condition, attempts to separate them, but they manage to reunite under the cloak of night in the garden, where they perform a magical rite to summon the spirits of the past and bring Colin’s father home.
Meanwhile, Lord Craven feels an inexplicable pull towards the garden of his late wife, prompting him to return unexpectedly to the manor. Following the laughter of children, he discovers Mary, Colin, and Dickon in the once-forgotten garden where he witnesses the miraculous transformation of his son. Their emotions culminate in a powerful reunion, underscoring the healing potential of love and the beauty of rekindling long-lost bonds.
As the seasons change and the garden thrives again, it serves as a metaphor for rebirth and renewal. Mary finds her place within this newfound family. She reflects on the lessons learned: her uncle learns to smile again, she begins to understand her emotions deeply, and the garden stands as a testament to life’s continuous cycle of growth and resilience. “If you look the right way, you can see that the whole world is a garden.” Through nurturing the garden, Mary uncovers not just the secrets of the past but her own heart, facilitating healing for herself, Colin, and Lord Craven along the way.
