In the waning light of 1899 rural England, a sprawling, isolated manor shelters a family whose very breath is tinged with dread. Within its stone walls, generations have learned to conceal a gruesome truth: each full moon summons a feral transformation that binds them to an ancient curse. The house itself feels alive, its corridors echoing with unspoken fears, while the surrounding countryside whispers of superstition and the inevitable return of darkness.
Pa Mooney dominates the household with a frail yet imposing presence, his claim of being 180 years old hanging over the family like a fragile cobweb. A retired doctor whose health falters, he spends his days poring over arcane research, convinced that the key to ending the blood‑bound affliction lies somewhere in his relentless studies. His authority is both a comfort and a source of tension, as the weight of his expectations presses on those who serve him.
Phoebe Mooney quietly shoulders the bulk of daily stewardship, managing the household with a weary steadiness that masks her inner resolve. Mortimer Mooney brings a pragmatic edge, overseeing the family’s finances and keeping their outward affairs from crumbling. In stark contrast, Monica Mooney exudes a volatile, animalistic temperament, keeping live rats as unsettling companions, while Malcolm Mooney dwells in a liminal space between man and beast, his confinement a stark reminder of the family's desperate attempts at control. Their interactions form a fragile tapestry of loyalty, resentment, and survival, each member navigating the thin line between humanity and the primal urge that the moon awakens.
The arrival of Diana—a newly qualified doctor returning from Scotland—shakes the household’s precarious equilibrium. Accompanied by her husband Gerald, a former classmate of Pa’s, she carries the promise of a fresh perspective; unlike the rest of the clan, she does not succumb to the nightly metamorphosis. Yet her presence is layered with personal secrets and motivations that hint at deeper currents beneath her poised exterior. The family watches, hopeful yet wary, as the prospect of finally breaking—or perhaps reshaping—their cursed legacy hangs in the charged night air.
