In the gothic splendor of 19th-century England, young author Edith Cushing finds herself drawn into a web of love, mystery, and danger. After a whirlwind romance with the enigmatic Sir Thomas Sharpe, Edith leaves her home in America and moves to the crumbling family mansion of Allerdale Hall, also known as Crimson Peak.
Thomas Sharpe, a charming yet troubled baronet, is devoted to his inventions, striving to resurrect the family’s fading fortune through a revolutionary clay-mining machine. His sister, Lady Lucille Sharpe, is fiercely protective and enigmatic, her icy demeanor hiding dark secrets.
As Edith settles into her new life, she begins to experience strange visions and ghostly apparitions. The mansion’s eerie whispers and shadows reveal tragic tales of murder and betrayal. Driven by her curiosity and the chilling warnings from beyond the grave, Edith delves into the Sharpe family’s sinister past.
Edith’s investigation uncovers a series of mysterious deaths linked to the Sharpe siblings. She learns that Thomas has been manipulated by Lucille, who harbors a twisted obsession with her brother. Lucille’s malevolent influence extends to the ghastly murders of Thomas’s previous wives, all for their wealth.
Thomas, torn between his love for Edith and his loyalty to Lucille, begins to see the monstrous nature of their actions. In a climactic confrontation, Edith and Thomas attempt to escape Lucille’s wrath. Amidst the bloodshed and chaos, Edith’s strength and resilience shine through.
In the end, Edith emerges from the horrors of Crimson Peak, forever changed by her harrowing experience. The ghosts of Allerdale Hall may linger, but Edith’s story is one of survival, love, and the enduring battle between light and darkness.
