Lizzie Fawkes has grown up in Radical circles where each step of the French Revolution is followed with eager idealism. But she has recently married John Diner Tredevant, a property developer who is heavily invested in Bristol's housing boom, and he has everything to lose from social upheaval and the prospect of war.
Soon his plans for a magnificent terrace built above the two-hundred-foot drop of the Gorge come under threat. Diner believes that Lizzie's independent, questioning spirit must be coerced and subdued. She belongs to him: law and custom confirm it, and she must live as he wants.
In a tense drama of public and private violence, resistance and terror, Diner's passion for Lizzie darkens until she finds herself dangerously alone.
