Young Mary Lennox is left an orphan when her parents die of illness while living abroad in India. Raised primarily by servants, Mary is left to mourn the loss of her inattentive parents before eventually being sent under the care of her Uncle in Yorkshire, England. It's there in Misselthwaite Manor that she meets two young boys - a young servant named Dick, and her cousin Colin who lives locked away in the manor due to a disability that leaves him bound to a wheelchair. Together the trio discover a secret garden locked away in the manor grounds. As they work to restore it, the three learn about each other, their families, and their own personal strengths.
