Sisters Connie and Jenny Dalton have always taken their comfortable lives for granted. They are sheltered from the deprivation which their housemaid Molly and her family endure in nearby Rotherhithe. But, in April 1912, their father leaves for a business trip to America - on the new ship Titanic... Within days William Dalton is resting in a watery grave. And, with his death, his widow and daughters learn that they have inherited only debt, with their home soon to be taken from them. As war approaches, it seems that the sisters' dreams for the future are to be snatched away. Yet new doors are about to open, behind which lie dangers and many changes - but also the possibility of happiness for both.
