A Welsh community is drawn together and blown apart by a strange vision in the mountains: the huge spectre of a woman floating over a ridge. The people who live here in these mountains already have their own demons - drink, drugs, domestic violence, psychoses - but each character has a different experience of this strange apparition, a different reaction, and for some it will change everything. Is it a collective hallucination? A meteorological phenomenon? Whatever it is, they all saw something, early one morning on the shores of a mountain lake, something that will awaken in them powers and passions and, perhaps, a possibility of healing these broken people in a broken country.
