John Thornton is facing the collapse of everything he has worked for all of his life. Through his banker, he hears about a potential business opportunity that could save the mill. He decides to investigate, even if it means traveling from home when he can least afford it. Margaret Hale, now living in London, learns that her godfather Mr Bell is visiting her brother Frederick in Cadiz. Bell is dying, and asking to see her before it is too late. She is determined to sail, regardless of the risk. An accident on the docks leaves Margaret injured, and throws both together on the same ship. Thornton, resolved to protect Margaret's honour despite their painful history, claims to be her brother to keep her safe. Unfortunately, pretending to be Margaret's brother proves more difficult - and more dangerous - than he might have expected.
