How do you know where you belong? In June 1988, Elizabeth Kelly's parents think she belongs at home in Ireland. Her boyfriend is certain of it. Unwilling to settle down just yet, she decides to spend the summer in Boston with her college friends. But the next four months change all of them, especially Elizabeth. Quiet and dutiful at home, she surprises herself and everyone else by falling for Danny Esposito, a restless charmer with a troublesome family. More than 20 years later with opportunities in Ireland scarce once again, a new generation looks to America, awakening memories of a golden summer for their parents. When a crisis occurs, Elizabeth returns to Boston where she is drawn back into the life she once lived. But will she be able to reconcile the dreams of her 20-year-old self with the woman she has become?
