[REC]⁴: Apocalypse is a Spanish horror film directed by Jaume Balagueró and released in 2014. It serves as the fourth and final installment of the [REC] series, bringing closure to the terrifying story that began with the viral outbreak inside a Barcelona apartment building. This time, the setting shifts from confined urban spaces to an isolated quarantine ship in the middle of the ocean, where the last survivors must confront the horror once again.

The film begins immediately after the events of [REC]². A military team is sent to rescue Ángela Vidal, the television reporter who was trapped inside the infected building. She is found alive and unconscious, and the soldiers bring her to a large ship that has been converted into a floating laboratory. The goal is to analyze her and search for any trace of the deadly virus that has turned humans into violent, demonic creatures. However, what the scientists do not realize is that the true evil has already boarded the ship.

As Ángela regains consciousness, she appears disoriented and claims not to remember what happened inside the building. The doctors run tests on her, but strange incidents soon begin to occur. Security systems malfunction, infected monkeys escape from the lab, and crew members start to disappear. It becomes clear that the demonic parasite carrying the virus has survived—and may still be inside Ángela herself.

Panic spreads throughout the ship as the infection rapidly takes hold. Soldiers and scientists must fight for their lives in narrow corridors while trying to prevent the virus from reaching the mainland. The ocean setting adds a new layer of claustrophobia and isolation, making escape impossible. The film combines military action with supernatural horror, keeping the tension high as the characters realize they are completely trapped with the infection.

Ángela, once a helpless reporter, becomes the unlikely heroine once again. She joins forces with a soldier named Guzmán to survive and uncover the truth about the parasite. As the story progresses, it is revealed that the demonic entity inside her may have developed a strange connection with her, blurring the line between host and victim. This twist adds emotional depth to the otherwise intense and bloody action.

Visually, [REC]⁴: Apocalypse abandons the found-footage style of the earlier films but retains the dark, frantic atmosphere that defines the series. The combination of tight spaces, flickering lights, and violent confrontations creates an unrelenting sense of dread. The sound design and practical effects make the horror feel raw and immediate.

In the end, the film concludes with Ángela fighting to destroy the parasite once and for all, leading to a fiery and explosive finale. [REC]⁴: Apocalypse closes the franchise with a mix of terror, tragedy, and survival, reminding viewers that even when the infection seems contained, true evil can never be completely erased.
