Great Grimsby, 1912. Newlywed fisherman Alec Hardy decides to make a fresh start with his young wife Letty and move to the thriving fishing port of Grimsby in search of a brighter future. Letty is from farming stock and knows nothing of the hard life as a fishermen's wife but is willing to embrace the challenge with Alec. But where Alec goes, so does his widowed mother, Dorcas and she has trouble coming to terms with taking second place in her son's life. With Alec at sea for weeks on end, the two women clash and Letty seeks escape from her bitter mother-in-law amongst the streets of Fish Dock Wharf. Can Letty help them break free from the shadows of the past or will she be bound by Dorcas' insistence that they cling to the old ways?
