The Boarding School - Season 4 (2008)

With the threat of death looming as he continues to pursue information about his missing mother, Marcos takes an extreme course of action to make a hospital connection that won't arouse suspicion.

Miguel convinces Paula and Lucas that Evelyn's sleepwalking comes from demonic possession. He highly recommends an exorcism in which water balloons figure predominantly.

Lieutenant Jimeno visits the school to investigate the death of Mateo Tabuenca, whose decaying corpse policemen found in the trunk of a teacher's car.

As the school remains a hot focal point of multiple mysteries and intrigue, Iván signs the papers acknowledging Jacques as his father, almost immediately aware of its depths as a bad move.

As more connections come to light between those at the school, Elsa awaits word on baby Samuel while Paula and Eveyln strive to prevent Jacinta's death.

Martín hopes the incredible nature of Lucas's latest prophetic dream (where Camilo collides with a flying unicorn) will prove them all insubstantial. Meanwhile, Julia sets out for her father's safety deposit box alone.

As the kids try again to undermine the murder dream, the gang deciphers the last book clue, the school elects a new principal, Julia leaves for good with her step-father, and Fermín's search for his father's killer pays off.

As the school celebrates its Night of the Twin Moons, several people put themselves in harm's way for the sake of another, and an unwary child playing sheriff roams the halls with a real gun.
