During the night of the eve of the Three Kings, a strong snowstorm named Mikaela devastates all of Spain. Leo, a police officer about to retire, finds himself on a completely congested highway where a group of thieves takes advantage of the situation to rob a van full of money that has become stuck. Due to the lack of resources for the police to reach the area, the security forces have no choice but to call Leo to try to stop the heist until the agents can arrive. Leo has nothing to lose, but the family waiting for him to celebrate the end of the Christmas season does. As he approaches the van, Leo encounters a young woman who encourages him to help in this difficult task. Together, they will try to prevent the robbers from escaping with the loot in a race against time through a snow-covered city.

This film is directed by Daniel Calpasoro ('Hasta el cielo' or 'Todos los nombres de Dios') and stars Antonio Resines ('Los Serrano') as Leo; and Natalia Azahara ('A través de mi ventana') as the young woman who helps the protagonist. They are joined in the cast by Roger Casamajor, Pavel Anton, Cristina Kovani, and Adriana Torrebejano ('La sombra de la ley') as the police officer in charge of coordinating the operation.
