When we meet Norah — the first member of her family to move from Ireland to New York — she is a mother of three, contemplating her husband’s casket as his men give him a full fireman’s funeral, and faced with a terrible choice. Norah's mother-in-law, Delia, is stoic and self-preserving. Her early losses have made her keep her children close and her secrets closer. Eileen, Delia’s daughter, adopted from Ireland and tough-as-nails, yet desperate for a sense of belonging, is one of the first women firefighters in New York. It is through her eyes that we experience 9/11, blindsided by the events of that terrible day along with her.
