The Best Episodes Written By Ciarán Donnelly

Dr. Mark Muir, a young American metallurgist, persuades American tycoon JP Morgan to hire him for the biggest shipping project the world has ever seen: RMS Titanic, at the Harland & Wolff shipyard, in Belfast. The shipyard's visionary Chairman takes the young scientist under his wing, introducing him to Belfast's Protestant elite. Mark quickly catches the eye of the charming, albeit spoilt, daughter of a magnate: Kitty Carlton. But he is also intrigued by a very different woman; Sofia Silvestri, an immigrant's daughter. Belfast, seen through Mark's eyes, is a city ridden with divisions of class and religion, from which, as a stranger, Mark should be far removed. But we soon discover that Mark is a man with a past mysteriously connected to the Catholic suburbs of Belfast.

Dr. Mark Muir's real name is Marcas Malone, and he is the son of a Belfast Catholic dockworker, Sean. Sean is an old drunkard, broken by a life of unimaginable harshness. His only remaining pride lies in Mark. Now, Sean is worried that if Mark's identity were to be disclosed, he would lose his job at the Protestant - managed shipyard. But Mark is careful and guarded. He starts finding out things about the steel used that lead him into conflict with chief designer Thomas Andrews. In the meantime, social tension escalates. A prominent figure in the labor movement, Jim Larkin, is organizing the workers in Belfast. While Kitty Carlton seduces Mark with her elegant charms, Sofia gets more involved in her fight for freedom, which she interprets in a personal way, turning down her father's apprentice, Andrea Valle, much to her father's grief.

Mark has put his father up in a small hotel. We learn that another man is looking for Mark, someone that Sean fears. Mark's job has made him closer to Sofia Silvestri. Sofia is charmed by Mark: he seems genuinely interested in her. Sofia's friend Emily warns to be careful. But Sofia has other worries. Her father is encouraging Andrea to fight for her. But Sofia won't be forced. In the meantime, Mark discovers a problem with the steel used to build the ship. But science is put to test by the divides in Belfast. The Protestant magnates, worried by the success of the Union, call in the Army to boycott a peaceful march. The Army sabotages the march in the Catholic area, causing accidents that seem organised by Catholic workers. Mark is there to show his respect for the workers.
