Tessa Wren returns with her husband, Miles, to Blackmoor House, the ivy-clad estate where her mother once lived and died. What begins as an attempt to grieve and sort her inheritance quickly unravels into something stranger: voices in the halls, shifting mirrors, and crimson letters that appear from nowhere, inked with warnings in familiar hands.

The house stirs memories Tessa cannot control, including the echo of Evelyn Wrenthrope - a vanished painter whose face, body, and desires feel terrifyingly close to her own. Tessa is drawn to Julian Rowan, the enigmatic caretaker of the family cemetery, whose warmth masks secrets he refuses to fully share. Their encounters blur the line between longing and haunting until Tessa no longer knows if she is seduced by Julian himself or by Evelyn's ghost that clings to him.

As the house tightens its grip, Tessa discovers hidden galleries of portraits: Evelyn, her mother, and countless other women who look like her, their images fading as though the house consumes them. A second presence emerges - the "Second Man," a shadow born of betrayal and obsession. His touch leaves stains of black ink on her skin. Evelyn's journals and crimson letters reveal the truth piece by piece: Julian is not untouched by the curse of Blackmoor. His life stretches impossibly across decades, tied to the house and to the women it keeps.

When Miles returns, desperate to save her, the full horror closes in. Tessa is trapped between three forces: Miles's steadfast love, Julian's dangerous immortality, and the Second Man's violent rage. The house itself becomes a predator, doors sealing, mirrors cracking, roses bleeding through the floorboards.

In the final confrontation, Tessa must decide whether to break free or be consumed like Evelyn - to choose love, truth, or survival. But the house has its own will, and when the ink dries, the line between muse and ghost may vanish forever.
