A seashell and a sealed letter form a tenuous connection to a forbidden wartime romance1937. Simon's Town is a vibrant and diverse community in a picturesque part of the Union of South Africa, with a Royal Navy port at the town's heart. Louise Ahrendts, daughter of a shipbuilder, nurtures the dream of becoming a nurse and in a world of unwritten, unspoken rules about colour, she has the strength to make it a reality. As the port becomes a hub of activity following the outbreak of the Second World War, Louise crosses paths with a man she is determined to be with - despite all the obstacles life and conflict throw in their way. But when a new troubled moment of history dawns, can they find their way back to each other?
