Paris in 1117. Heloise, a brilliant young scholar, is astonished when the famous, radical philosopher, Peter Abelard, consents to be her tutor. But what starts out as a meeting of minds turns into a passionate, dangerous love affair, which incurs terrible retribution.
Nine centuries later, Arthur is in Paris to recreate the extraordinary story of Heloise and Abelard in a novel. To his surprise, his daughter visits and agrees to help, challenging his portraits of a couple who seem often inscrutable, sometimes breathtakingly modern. It soon emerges she is on her own mission to discover more about her parents' fractured relationship - and that Arthur's connection to his subject is more emotional than he cares to admit.
