Nobody ever goes to Hartwood Hall. Folks say it's cursed...

It's 1852 and Margaret Lennox, a young widow, attempts to escape the shadows of her past by taking a position as governess to an only child, Louis, at an isolated country house in the west of England.

But Margaret soon starts to feel that something isn't quite right. There are strange figures in the dark, tensions between servants, and an abandoned east wing. Even stranger is the local gossip surrounding Mrs. Eversham, Louis's widowed mother, who is deeply distrusted in the village.

Lonely and unsure whom to trust, Margaret finds distraction in a forbidden relationship with the gardener, Paul. But as Margaret's history threatens to catch up with her, it isn't long before she learns the truth behind the secrets of Hartwood Hall.
