South Korean filmmaker Yeon Sang-ho, best known for the global zombie hit Train to Busan, is set to return to the spotlight with his latest project, Colony, which Chad Collins called “furious, terrifying, and a new zombie classic!”

Colony marks Yeon’s return to the zombie thriller genre, following survivors trapped in a quarantined building during an infection outbreak, battling ruthless infected beings.

A blood-soaked new image from Sang-ho’s upcoming horror thriller teases another frantic outbreak nightmare from the filmmaker behind Train to Busan.

The film follows Professor Se-jeong as she is thrust into a terrifying hellscape when a mutating virus is unleashed during a biotech conference, forcing authorities to seal the facility to contain the outbreak. Unable to escape, Se-jeong and a group of survivors must fight to stay alive as the infected undergo horrific transformations and threaten to spread the virus. 

The film stars Jun Ji-hyun, Koo Kyo-hwan, and Ji Chang-wook, bringing together a high-profile cast for what is expected to be an intense, character-driven survival story.
