If Train to Busan had you gripping your seat, brace yourself — the same director is back, and Colony looks even more terrifying.
What Is Colony About?
Colony follows the story that unfolds as a building is blockaded due to an unknown virus, as those infected evolve into unpredictable forms, threatening the survivors inside.
Think claustrophobic dread, mutating threats, and two ex-lovers forced together in the worst possible circumstances. Yes, we’re already hooked.

Go Soo’s Character — A Hero Trapped by Fate
Go Soo plays Han Kyu Seong, a biotechnology professor and Se Jung’s ex-husband. On the day before his planned move to the United States, Han Kyu Seong visits Dungwoori Building to offer a job opportunity to his ex-wife, who failed to secure reappointment as a professor — but he unexpectedly becomes trapped inside.
Talk about wrong place, wrong time. What starts as a simple act of kindness spirals into a life-or-death battle.
As he hides from the infected who suddenly rush in, he discovers other survivors in danger and becomes the first to be exposed while trying to save them — boldly stepping into danger for others despite the risks.
Go Soo described his character as “a figure who serves as a gateway from ordinary daily life into a cinematic world where the infected suddenly attack,” adding that he hopes to convey the warmth that humans possess to the audience.
Why Colony Could Be 2026’s Biggest Korean Horror Film
The name Yeon Sang Ho alone is reason enough to pay attention. The mastermind behind Train to Busan — one of the most celebrated Korean films globally — returns to his signature survival-horror territory. The new stills heighten tension by placing Han Kyu Seong in imminent crisis, his once warm gaze shifting to sharp vigilance as he carefully observes a situation where he cannot let his guard down. soompi
Pair that with Jun Ji Hyun, one of Korea’s biggest stars, and Colony has blockbuster written all over it.
