Cemetery of Terror

Jorge and Oscar trick their friends Pedro, Lena, Olivia, and Mariana into breaking into the large abandoned mansion for a Halloween party. They present it as a different type of event to lure everyone there, underestimating the danger inside.

Dr. Cardan is informed that Devlon escaped from a psychiatric hospital and was killed in the process. Aware of Devlon's power, he seeks a judge's clearance to have Devlon's body cremated.

The group breaks into the university hospital morgue and steals one of the corpses, unaware that it is Devlon's. Cardan arrives at the morgue to have Devlon's body cremated, but finds that the body has already been taken.

The group brings Devlon's body to a cemetery where Jorge performs a ritual to bring it back from the dead. The ritual frightens everyone and they flee back to the mansion, unaware that Devlon has been resurrected.

Back at the house, Mariana is attacked and killed by Devlon on the porch. The others are stunned as his power becomes unmistakably real.

Oscar finds Mariana's body outside and is himself attacked and killed by Devlon. The rampage inside the mansion continues to claim more lives.

Olivia goes to investigate the noise outside and discovers Oscar's corpse, causing her to flee into the house in hysterics. The situation grows increasingly chaotic as the night unfolds.

Devlon proceeds to kill Jorge and disembowel Olivia. Lena is stabbed to death upstairs as the assault spreads through the house.

Pedro, watching Lena's death through the window, arms himself with a hatchet. The weapon begins to levitate on its own and bludgeons him to death.

Tony visits the cemetery with Usi, Cesar, Anita, and Raúl and sees Devlon's tomb burst into flames, sending them running for shelter in the abandoned house. They realize the danger has followed them.

Devlon appears and chases the children upstairs in the house. Tony arms himself with the hatchet and prepares to flee as horrors rise around them.

Cardan reaches the cemetery to help the children and wards off the undead with a crucifix. The kids retrieve Devlon's book and throw it into the fireplace, causing the undead to burst into flames. Police arrive to rescue the children. Cardan returns the charred book to the attic altar, which is now possessed by Devlon.
