Florence Connelly is broken hearted. Her marriage has collapsed under the weight of the loss she shares with her husband, and her beloved grandmother has just died. Even the joy she found in dressmaking is gone. But things change when Flo opens a box of vintage 1960s dress patterns found inside her grandmother's wardrobe. Inside each pattern packet is a fabric swatch, a postcard from Europe and a photograph of a mysterious young woman, Nancy Moon, wearing the handmade dress. Flo discovers that Nancy was a distant relation who took the boat train to Paris in 1962 and never returned. With no one to stay home for, Flo decides to follow Nancy's thread. She unravels an untold story of love and loss in her family's past. And begins to stitch the pieces of her own life back together.
