Bilbao, 1914. Amelia Eguren, daughter of an illustrious family, is about to marry a man she barely knows. Behind their engagement there are many hidden interests, some of which she does not even suspect. While he is the owner of one of the most prosperous businesses in the city, Amelia runs the La Blanca soda factory in the shadows, so this alliance could bring her everything she has always fought for.

However, when Irune, a humble cleaner, comes to work in the factory, her perception of the world changes, and between the two of them an unexpected bond emerges that transcends prejudice. Over the course of four decades, these two women struggle to survive and cling to love in a turbulent time when war, disease and the struggle for freedom shake their homes.

With an enveloping narrative full of emotion, Elena Peña takes us to a bustling Bilbao at the dawn of the 20th century, profiling two unforgettable protagonists.
