Every family has its ghosts…

When three innocent children play a game that ends in fatal consequences, it sets in motion a series of events that will haunt their family forever…

After the horrors of World War One, disillusioned army chaplain John Elliot arrives at Hern Hall, an isolated estate in the mist-shrouded English countryside. The mystery of the estate's tragic past seems to linger in the shadows when John catches a glimpse of a drowned child's face beneath the dark waters of the lake.

Though he suffers from shell shock, John is determined to keep a promise he made to his friend Will, who died in the trenches while saving John's life. Before meeting Will's grieving parents, Lord and Lady Chiddingstone, John first encounters Will's sister, Lucy—a beautiful, blind, and mysterious young woman.

Invited by Lord and Lady Chiddingstone to stay as a guest at Hern Hall, John experiences a series of unsettling and eerie events, including attending a seance led by the infamous spiritualist medium, Madame Blanche, whom Lady Chiddingstone hopes can communicate with her dead sons.

As John grows closer to the family, he uncovers more about their traumatic past and the disturbing secrets hidden within the walls and tunnels of Hern Hall. Is the family cursed, as an ancient legend suggests?

Can the ghosts and the living ever find peace, or are they destined to be forever haunted by death?
