"She came to wed him. She stayed to break a curse written in blood."
In the mist‑shrouded halls of an ancestral castle, Crimson Vow weaves a haunting tale of devotion, legacy, and the price of eternal promises. Once a symbol of unity, the castle now pulses with ancient magic—each blade of crimson sealing a pact with fate.
Isabella (Florence Pugh), betrothed to Lord Lucien (Dev Patel), arrives to fulfill a political alliance that has bound two powerful houses for centuries. The ceremony is lavish, the vows spoken in candlelit grandeur—but under the moon’s gaze, something awakens. When Lucien inexplicably refuses to drink the ceremonial wine, Isabella finds herself trapped in a web of old bloodlines and darker intentions.
By midnight, she uncovers the castle’s curse: every generation, a bride must offer the first drop of her own blood—not to bond, but to bind the lineage—and without it, the houses tear each other apart. Isabella must choose: sever the bloodline and save countless lives, or seal her love with a sacrifice that may consume them both.
Set against thick tapestries, gargoyled stone, and corridors soaked in ritual, Crimson Vow pulses with gothic romance and supernatural dread. As Isabella races to break the curse, she and Lucien confront not only each other—but the ancestral sins bleeding through their family tree.
