Nice, France, 1911: After three years of marriage, young seamstress Marcela Caretto has finally had enough. Her husband, Michael, an ambitious tailor, has become cruel and controlling and she determines to get a divorce.

But while awaiting the judges decision on the custody of their two small boys, Michael receives news that changes everything. Meanwhile fun-loving New York socialite Margaret Hays is touring Europe with some friends. Restless, she resolves to head home aboard the most celebrated steamer in the world RMS Titanic.

As the ship sets sail for America, carrying two infants bearing false names, the paths of Marcela, Michael and Margaret cross - and nothing will ever be the same again.m
