Colony tells the story of survivors trapped in a building that has been blockaded due to an unknown virus, as those infected evolve into unpredictable forms. Think claustrophobic tension, moral chaos, and a cast good enough to make you forget you’re watching fiction. It’s a natural evolution of Yeon Sang Ho’s signature style — grounded human drama wrapped inside genre-defining horror.
