Five men and women are trapped in an elevator. A murder occurs in the sealed elevator, leaving them unable to escape. Then, suddenly, another murder happens. The killer is among them, and everyone is consumed by suspicion. Blaming the murders on demons might seem too simple, but the film makes great use of the elevator setting to explore guilt and suspicion. The way the characters interact maintains high psychological tension throughout. Fans of American dramas like The X-Files or Supernatural will likely enjoy it. It feels more like a two-part extended episode than a single one.
