When Evil Lurks

Pedro and Jaime are abruptly awakened by the sound of gunfire in the nearby woods. Their curiosity propels them to investigate the noise, setting them on a dark path of discovery.

The boys stumble upon the mangled body of a man in the woods, shocking them to their core. This find leads them to a dilapidated shack where they meet María Elena and her terrified sons.

In the shack, they learn that Uriel, the eldest son, is facing dire consequences as a 'Rotten.' His condition stems from the threat of an unborn demon, which María Elena sought to end with the help of a 'Cleaner.'

Despite the grim circumstances, the local authorities dismiss the situation, labeling it as someone else's issue. This neglect deepens the family's sense of isolation and desperation.

The landowner, Ruiz, decides to rid himself of Uriel by driving him away from the area. However, his plan backfires when Uriel falls from the truck, narrowly avoiding an encounter with a young boy.

The following morning, Jimena finds one of their goats in a terrifying state, its eyes glowing with malevolence. Her warnings go unheeded as Ruiz kills the creature, leading to tragic consequences.

Overwhelmed by despair after the goat's death, Jimena turns on Ruiz with an axe before taking her own life. This event marks a pivotal turning point in the family's unraveling.

Realizing their situation is dire, Pedro and Jaime decide to flee the town for safety. Pedro heads to his ex-wife Sabrina's home, leading to tense confrontations.

The once-innocent family dog, now corrupted by Pedro's tainted clothes, brutally attacks Vicky, Sabrina's daughter. This unexpected violence forces Leonardo to shoot the pet in a moment of desperation.

As Pedro speeds away with his sons, he witnesses a horrific crash where Leonardo tries to save Vicky and Sabrina. Despite the chaos, he manages to escape with his children.

The family seeks refuge at Mirta’s house, where they learn Jair, one of the sons, is showing signs of possession. Mirta's warnings about the dangers ahead begin to be taken seriously.

Sabrina's reanimated corpse kidnaps Santino, causing panic among the remaining family members. Mirta instructs Jaime to pursue and rescue him from this terrifying fate.

Jaime learns the horrifying truth when he drives into a tree, consumed by grief over Santino's abduction. His despair marks another significant blow to the family.

Pedro and Mirta's search for Uriel leads them to a school overtaken by possessed children. Their confrontation escalates as they realize the children are plotting to facilitate the demon's birth.

In a moment of desperation, Pedro inadvertently triggers the demon's birth from Uriel’s lifeless body. This unleashes an entity that cruelly torments Pedro before vanishing into the light.

Returning home, Pedro faces the terrifying revelation that Jair has succumbed to possession through sinister means. Overwhelmed by grief and despair, he collapses outside as darkness closes in around them.
