Elisa Mander is found dead in a luxury hotel on a storm-lashed islet near Mallorca, where thirteen guests are stranded. What initially looks like suicide soon becomes a murder investigation, and everyone, guests and staff alike, is a suspect.
The story is set in spring 1959. Netflix’s new miniseries El problema final drops viewers into a closed world where no one can leave. Heavy weather cuts off the hotel; as the hours pass, trust frays and suspicion grows. Elisa Mander, a quiet English tourist, is only the first victim. Motives and secrets surface as the investigation grows more tangled. The official Netflix premiere date for El problema final is September 25, 2026, and the series will consist of four episodes.
Basil, played by Jose Coronado, is at the center of the story. A retired actor once famous for playing Sherlock Holmes, he is forced to investigate. He doesn’t want the job, but the tension leaves him no choice. Adela Figueroa (María Valverde), a mysterious young woman, and her friend are also there. Foxá (Martiño Rivas), a thriller writer, joins them, with grim reality testing his imagination. Together, they search the hotel’s dark corners. The manager, señora Ausländer (Maribel Verdú), tries to keep control, but the list of suspects keeps growing and the truth slips further away.
The cast also includes Gonzalo de Castro as Fonseca, an ambitious film director, and Cristina Kovani as a young actress. José Condessa and Pepón Nieto are among the others in the group. Alberto Macías and Carlos Molinero wrote the script, with Marisol Farré also credited, while Félix Viscarret directs all four episodes. Every character joins the search for answers as alibis and motives are picked apart. The storm outside mirrors the chaos inside.
Information from EFE, lead actor Jose Coronado describes the series as an intellectual game that invites viewers to solve the mystery actively, rather than watch the plot unfold passively. That approach makes El problema final a classic whodunit for fans of intricate detective stories.
The series is based on a best-selling novel by Arturo Pérez-Reverte. Its 1959 setting heightens the sense of isolation and paranoia, while the thriller promises sharp twists and a close look at how people act under pressure.
Netflix’s adaptation reflects demand for smart Spanish-language thrillers rooted in literature and film. Set in a specific time and place, El problema final joins Netflix’s international lineup for viewers drawn to suspense and atmospheric mysteries that keep their secrets close.
