In the bitter winter of 1847, from an Ireland torn by injustice and natural disaster, the Star of the Sea sets sail for New York. On board are hundreds of fleeing refugees, some brimming with optimism, many more desperate. Among them are a maidservant with a devastating secret, bankrupt Lord Merridith and his wife and children, an aspiring novelist, a maker of revolutionary ballads, all braving the Atlantic in search of a new home.
