The Secret Garden [VHS]

From Wikipedia: When tempestuous Mary Lennox, born in India to wealthy parents, is orphaned by a cholera epidemic, she is sent to live with her reclusive and embittered Uncle Archibald Craven and her ill-behaved, bedridden cousin Colin at their desolate and decaying estate known as Misselthwaite Manor. Dickon, the brother of one of the house maids, tells her of a garden secreted behind a hidden door in a vine-covered wall. When a raven unearths the key, the two enter and discover the garden is overgrown from neglect since Craven's wife died there in an accident. They decide to keep their discovery a secret, and begin to restore it to its original grandeur. Under the influence of the Secret Garden, Mary becomes less self-absorbed, Colin's health steadily improves, and Archibald's curmudgeonly personality fades away.
