Netflix today unveiled the official trailer and new images for The Final Problem, the limited series starring Jose Coronado (The Truthers, The Snow Girl), María Valverde (Sounds Like Love, All We Cannot See), Martiño Rivas (Snakes and Ladders, Cable Girls) and Maribel Verdú (Pan's Labyrinth, Elite), among others. Based on the successful novel of the same name by acclaimed author Arturo Pérez-Reverte, the series premieres on Netflix on September 25.

This new miniseries, which combines thriller and mystery against an immersive period backdrop, consists of four episodes and features a first-rate ensemble cast, including Gonzalo de Castro (Políticamente incorrectos, La ternura), Cristina Kovani (Muted, La caza: Guadiana) , José Condessa (Cacau, Turn of the Tide) and Pepón Nieto (Smiley, A Remarkable Tale ), among others.

In the spring of 1959, thirteen people find themselves stranded by a violent storm on a small island off the coast of Mallorca. No one could imagine what is about to unfold at the secluded hotel where they are staying: Elisa Mander, a quiet English tourist, is found dead. What initially appears to be a suicide soon reveals itself to be something far more disturbing: a murder. Basil, a retired actor who once portrayed none other than Sherlock Holmes on the big screen, finds himself, almost unwittingly, tasked with uncovering the truth behind what happened.

In a place that no one can leave and no one can reach, every guest and employee becomes a suspect in a crime that, with each passing moment, proves to be far more complex and intricate than anyone could have initially imagined. The Final Problem is a sophisticated adaptation of one of Arturo Pérez-Reverte’s bestselling novels, a period thriller packed with secrets, mystery and unexpected twists. This new miniseries, which blends thriller and mystery against an immersive period backdrop, consists of four episodes.

The miniseries is produced by Mod Producciones, with Fernando Bovaira (While at War, La Fortuna) serving as producer, Urko Errazquin (The Champion, Two Many Chefs) as executive producer, and Alberto Macías, Carlos Molinero, and Marisol Farré as screenwriters. It is directed by Félix Viscarret (Una vida no tan simple, Staring at Strangers ).
