Sisters Nora and Theresa Flynn leave Ireland for America, seeking new lives. Nora, reserved and unsure about her engagement, contrasts with the vivacious Theresa, who embraces the Boston scene until an unplanned pregnancy upends their plans. Decades later, as Nora commands a large family and Theresa lives in secluded piety, a death forces them to face the long-lasting impact of past decisions, knitting a tale of family, faith, and the unspoken bonds that endure through generations.
