The Boarding School: Las Cumbres Season 4 is to Premiere on Amazon Prime

Lights in the sky have always been a bad omen. And tonight, the sky is filled with lanterns.

Frustrated at not being able to report Corax's crimes, the kids react with anger. They'll soon discover that their worst nightmares might just become a reality.

Manuel's return to the boarding school arouses Paul's suspicions. Is his behaviour a natural reaction to the traumatic experience he's been through, or is he hiding something?

While continuing their investigation into Inés and León's true identities, an unexpected arrival surprises the students, putting all their plans on hold.

The incessant struggle to expose all the secrets the boarding school keeps hidden eventually leads the students to an even greater revelation… Who is Inés, really? And what does she have to do with what's happening to them in there?

The students, increasingly beaten down by the measures inflicted on them by the boarding school, find proof that would prove everything to the police. How can they get it to the outside world from inside this prison?

After finding out who kidnapped Manuel, Paul and Amaia keep their eyes on the culprit. Their tireless pursuit takes them to sinister locations where they discover a great mystery surrounding León... and perhaps Inés too?.

Following the student rebellion over the death of Elías, Las Cumbres Boarding School has become harsher and more hostile than ever. But now that Amaia and Paul know that Adèle has seen Manuel alive, they won't rest until they find him.

The friends mourn Manuel. The prior discovers Elías has broken his vow of chastity and sends him to another monastery. Meanwhile, Elvira tries to share everything she knows and Inés starts putting pieces about her past together. But a new and unexpected death enrages the students, who start a rebellion at the school. Everything is out of control and we're in for an unexpected ending.

We go back in time to find out what happened to Manuel after he was taken by a masked man. His friends are convinced someone kidnapped him and try to get inside the Crow's Nest, where they assume he's being held. Meanwhile, Elías thinks he's discovered what's causing Eric and other students' symptoms and who is behind it.

Amaia and Paul manage to find the Crow's Nest. Meanwhile, Inés wakes up confused in the middle of the woods and when she sees León, she runs in terror. We go back in time to discover the secret behind Inés' connection to León. Eric suffers another episode of memory loss. Elías notices some strange behaviors, which start to raise his suspicions.

The Las Cumbres prior believes the devil runs rampant in the monastery. Amaia discovers a supernatural tie between her and Inés. Elías feels extremely guilty after what happened with Elvira. Meanwhile, Paul finds something in his cell that makes him suspect the friar. Eric suffers a strange blackout and Paul and Amaia follow a clue to find the Crow's Nest.

Adéle blames Amaia for the party and she's accused of tattling. Paul and Amaia take Paz and Eric to see a mysterious painting with crow-men, but they find something terrifying instead. Inés undergoes treatment and takes pills that give her hallucinations. Elías and Elvira feel an increasingly irresistible attraction and Paul and Amaia will discover something about Las Cumbres.

Adéle tells Alba's secrets, which surprise everyone. Darío takes his daughter Inés home, near the school, where she has very strange visions. An unexpected postcard from Manuel assuring that he's all right discredits Amaia's story about his disappearance. León sneaks into Darío and Inés' home, the students organize a secret party and Elías and Elvira grow closer.

Amaia is lost in the woods when she's found and taken back to the school. There, she becomes obsessed with convincing Paul and his friends of what she saw and reporting it. But students at the school are cut off from the outside world. In the library, they find drawings of men wearing bird-like masks that confirm Amaia's story, but something terrible shocks them all.

Las Cumbres Boarding School is an impenetrable fortress built on the edge of a cliff where students are subjected to strict discipline and it seems impossible to escape. However, two of them manage to run into the woods one night, but things take a turn for the worse because surviving outside the school is even more dangerous than inside and the woods are much more terrifying.
