Young college student Kat O'Callahan has heard all her life the story of the 19th century coffin ship from Ireland that brought her great-great-great grandmother Sarah to America when she was young. And of the mysterious disappearance of Sarah's father from the ship in the middle of the Atlantic Ocean during the voyage.
Kat senses that Sarah and her strong women descendants are closely connected to her through long-hidden family stories. This inherited past, together with her art and college studies, help her when the dark legacy of the coffin ship comes unexpectedly into her life. Kat is kidnapped by Shawn Mahoney, a direct descendant of one of the men responsible for the coffin ship robbing and killing of her ancestor.
This violent kidnapping leads to a long night of memory and soul searching about what led to this fateful coming together of their lives. Kat draws on her strong women ancestors who talk to her in her captivity. Meanwhile, her kidnapper reveals how his life has perpetuated the curse inherited from the coffin ship. Kat delivers a form of delayed justice for her ancestor and learns the importance of hearing the voices, dead and alive, from one's past.
