Following the unusual connection made between four workers at different stages of their lives, Under the Snow captures factory life in a way rarely seen: personal, flirtatious, introspective. With the winter season fast approaching and orders piling up in the snow chain division, supervisor Javier and shy assistant Jairo are joined by temporary workers, Karmentxu and Angela. For long, frigid days they each pack chains in silence until Angela starts breaking the rules - then work becomes a game and that cold, gray building a playground. This newfound camaraderie challenges them to look at what they demand of their lives and of each other, but this world only survives thanks to the continuous snow. What is going to happen when the snow ceases to fall?
