Nunswept (also seen as nun-swept) is from the movie The Miracle, a 1991 drama film written and directed by Neil Jordan.
Young talents Niall Byrne and Lorraine Pilkington play Jimmy and Rose, best friends who spend their days on the cobbled streets, foggy palisades and "nun-swept piers" of Bray, Ireland. Possessed of a rich imagination and a gift of gab, Rose has drawn Jimmy into a game of making up stories about the locals and tourists in the seaside town. They are wildly romantic fictions, tales of unrequited love, murdered husbands and other purple passions.
The acting in this film is superb and the language is even better. As Rose and Jimmy wander around town making up scenarios, she uses such descriptions as "figures on a nunswept pier," for the people in her line of vision. Wilmington Town Crier
