The Orphanage

The story begins with Laura returning to her childhood orphanage in Spain, accompanied by her husband Carlos and their young son Simón. Laura's intention is to renovate the crumbling building into a caring home for disabled children, rekindling her own memories from the past.

Upon their arrival, Simón claims to have a friend named Tomás, who he describes as a boy wearing a sack mask. This revelation confuses Laura, who wonders about the nature of her son's new friendship, raising questions about its implications.

Benigna, a social worker, unexpectedly visits Laura and presents Simón's adoption file, igniting Laura's anger. That night, Laura catches Benigna snooping around her garden shed but fails to confront her before Benigna escapes.

Simón introduces Laura to a game inspired by Tomás, which involves hiding personal belongings. During this game, Laura realizes that Simón's adoption file has gone missing, heightening the tension between mother and son as they argue about its whereabouts.

In a distressing moment, Simón insists that Tomás has revealed to him that Laura is not his real mother and that he is destined to die. This alarming claim plunges Laura into a state of worry and confusion about her son’s well-being.

During a festive party at the orphanage, tensions peak between Laura and Simón. As he seeks refuge from her, Laura encounters a mysterious boy in the sack mask, who traps her in a bathroom. This encounter raises her anxiety about Simón's safety.

Frantically searching for Simón, Laura spots a shadowy figure in a cave. When she rushes towards it, she stumbles and injures herself, adding to her desperate and chaotic emotional state as she fears for her son's safety.

After learning from police psychologist Pilar that Benigna may have abducted Simón, Laura becomes increasingly frantic. Later that night, unsettling noises from the walls of their home intensify Laura's fears, suggesting a haunting presence.

While out downtown, Laura spots Benigna pushing a stroller, but tragedy strikes when an ambulance hits Benigna, killing her. Laura discovers a doll with Tomás's sack mask in the abandoned stroller, deepening the mystery surrounding Simón's disappearance.

The investigation reveals Benigna's past connection to the orphanage, including the tragic death of her son Tomás. Pilar shows Laura a photograph, stirring up memories and drawing a connection to the horrific events that transpired at the orphanage.

In her frantic quest, Laura consults a medium named Aurora, who tells her that she is close to death and will see those who have passed. This revelation terrifies Laura but also triggers a series of supernatural encounters.

Overwhelmed by the haunting atmosphere, Carlos decides to leave the orphanage while Laura takes sedatives to cope. In an induced near-death state, she hallucinates and begins to interact with ghostly children who guide her to a hidden door in the basement.

In the basement, Laura discovers Simón alive, wrapped in a blanket. She urges him to envision a brighter future to help the spirits around them, pushing against the dark energies that have plagued them since their arrival at the orphanage.

To her horror, Laura finds a lifeless body wearing Tomás's mask hidden beneath the stairs. As she removes the mask, she discovers it is Simón, realizing that barricading the basement led to his tragic fate, sending her into a spiral of grief and despair.

In a moment of heartbreak, Laura takes pills in a final attempt to reunite with Simón. The spirits of lost children surround her, and she embraces Simón once more, while outside, Carlos confronts the tragic loss of his family.
