Professor Se-jeong is thrust into a bloody nightmare when a rapidly mutating virus is released during a biotech conference causing authorities to seal the facility. Trapped inside with no escape, Se-jeong along with a small group of survivors must fight to stay alive while the infected undergo horrific transformations.
Yeon Sang-ho directs this 2026 action-horror thriller, in which a professor is trapped inside a sealed biotech conference after a fast-mutating virus is unleashed, forcing a small band of survivors to fight for their lives as the infected undergo grotesque transformations. The tone is tense and relentless, combining outbreak dread with claustrophobic survival horror. Themes of panic, containment, and humanity tested under extreme pressure drive the story. With a MagicMovieScore of 7.0, it's well suited to fans of intense infection thrillers and confined-space horror who enjoy high-stakes survival scenarios and the visceral terror of a contagion spiraling out of control.
