The woods outside Las Cumbres do not forgive. That is the first rule of The Boarding School: Las Cumbres, and it is the engine that drives all 22 episodes across three seasons. The Spanish mystery drama premiered on Prime Video on 19 February 2021 and ended its run on 6 April 2023. It is a reboot of El Internado, which aired from 2007 to 2010. A boarding school for troubled teenagers sits in an ancient monastery, cut off from the world. The students are rebellious. The discipline is severe. The forest holds legends that are still valid.
That last detail matters. The Boarding School: Las Cumbres is not a show about reforming wayward youth. It is a show about what happens when four of those youths try to run, and one of them does not make it out.

Manuel Villar Never Reaches the Gate
The series opens with a breakout. Four students — Manuel Villar, Amaia Torres, Paul Uribe and his sister Adele Uribe — plot to escape Las Cumbres. Adele backs out at the last minute. Paul cannot bring himself to leave his sister behind. So Amaia and Manuel run into the woods alone. Manuel stumbles and is knocked out. Amaia watches a dark figure in a plague doctor’s mask, a crow’s mask, pick him up and carry him away.
When Mara the headmistress and Mario the gym teacher catch Amaia, they dismiss her story as hysterical nonsense. That dismissal is the show’s real inciting incident. Amaia and Paul, later joined by their friends, set out to find Manuel. Their search leads to an ancient secret society: La Logia del Nido del Cuervo, the Raven’s Nest Lodge. It also leads to other mysteries buried at Las Cumbres.
The setup is efficient. The Boarding School: Las Cumbres does not waste time on a slow build. It puts a masked figure on screen early and lets the questions pile up. Who took Manuel? What does the lodge want? Why does the monastery have so many locked doors?
A Monastery Between the Mountains
The setting does most of the work. Las Cumbres is isolated between mountains, next to an old monastery. The students live under strict discipline meant to reintegrate them into society. The surrounding forest is home to ancient legends and threats that remain valid. That phrase — threats that are still valid — is the show’s thesis. The past is not past here. The monastery’s history is active, and the forest is not a backdrop. It is a character.
The show’s genre is listed as drama and mystery, with teen thriller elements. The Spanish title is El Internado: Las Cumbres. It was produced by Atresmedia Studios and Globomedia, part of The Mediapro Studio. Three seasons, 22 episodes total. That is a compact run by streaming standards, and it gives the series a tighter shape than many of its peers.
The cast is large and the show uses it. Albert Salazar plays Paul Uribe. Daniela Rubio plays Adele Uribe. Carlos Alcaide plays Manuel Villar. Claudia Riera plays Inés Mendoza, also credited as Alicia. Mina El Hammani plays Elvira, the science teacher. Joel Bosqued plays León, the music teacher. Natalia Dicenta plays Mara, the director of the boarding school. Lucas Velasco plays Mario, the physical education teacher. Kandido Uranga plays Arturo, the monastery abbot. Alberto Amarilla plays Elías, a monk and Latin teacher.
That mix of students and staff is where the show gets its tension. The adults are not neutral. Mara and Mario dismiss Amaia’s account. Arturo runs the monastery. Elías teaches Latin, which in a show about an ancient lodge is not a small detail. The staff know more than they say, and the show lets that suspicion sit.
The Raven’s Nest Lodge
The Raven’s Nest Lodge is the show’s central mystery. It is an ancient secret society, and the search for Manuel pulls the students toward it. The Boarding School: Las Cumbres handles this thread with patience. It does not dump the lodge’s history in one scene. It lets the students find pieces, and it lets the audience wonder which adults are inside it.
The plague doctor mask is the show’s best image. A crow’s mask on a dark figure in the woods is a clear, frightening visual, and the show returns to it. It works because it is simple. No explanation is needed for a masked figure carrying a boy through trees. The fear is built in.
Claudia Riera’s dual credit as Inés and Alicia is the kind of move a mystery show makes when it wants to complicate its own history. The show’s three-season run gives it a defined shape from the start. That is a point in its favor.
Where the Middle Sags
The strongest part of The Boarding School: Las Cumbres is its refusal to soften the school. Las Cumbres is not a charming campus with a dark secret. It is a disciplinary institution for “problem children,” and the show treats the students’ anger as reasonable. They are not wrong to want out. The adults who run the place are not trustworthy. That clarity gives the mystery stakes.
The weaker part is the middle. With 22 episodes across three seasons, the show has room to wander, and it does. The lodge thread can stall while the show services its teen drama. The romance and rivalry beats are standard for the genre, and they do not always earn their screen time. When the show focuses on the forest, the mask and the monastery, it is sharper.
The cast keeps the weaker stretches watchable. Natalia Dicenta’s Mara is a headmistress who can dismiss a missing student as fantasy without flinching. Lucas Velasco’s Mario is a gym teacher who backs her up. Joel Bosqued’s León and Mina El Hammani’s Elvira give the staff a second layer. Among the students, Albert Salazar’s Paul carries the emotional weight of a brother who stayed behind.
The show also knows how to use a small detail. Elías the monk teaches Latin. The monastery is old. The lodge is ancient. None of that is accidental. The Boarding School: Las Cumbres builds its mystery out of things that predate the students, and that gives the horror a longer shadow.
Why the Reboot Holds Up
Reboots usually fail because they copy the original without understanding it. El Internado ran from 2007 to 2010 and became popular. The Boarding School: Las Cumbres takes the same core — a boarding school, a missing student, a secret society — and moves it to a monastery between mountains. The isolation is tighter. The forest is more active. The discipline is harsher.
That is the right call. Las Cumbres takes a closed world and makes it smaller and stranger. The result is a show that feels like its own thing rather than a rehash.
The audience score on TMDB is 7.5 out of 10, drawn from 901 votes. That figure is a reasonable match for what the show delivers. It is not a flawless series. It is a well-built mystery with a strong setting and a cast that commits.
What Las Cumbres Gets Right
The Boarding School: Las Cumbres is a show about a place that does not let anyone leave. Manuel tries. Amaia tries. The forest takes one of them, and the adults pretend nothing happened. That is the show’s real horror: not the crow’s mask, but the headmistress who calls a missing boy a fantasy.
The show earns its score by knowing what it is. It is a teen mystery with a gothic setting, and it does not pretend to be more. The lodge, the monastery and the forest give it a mythology that holds across three seasons. The teen drama drags in places, and the middle stretch could be tighter. But the core is solid.
What matters most is the discipline of the premise. Las Cumbres is not a school. It is a trap with a curriculum. The students are right to run, and the show is right to follow them into the woods. The mask is waiting there, and so is the lodge.
