Years after the zombie outbreak that decimated Korea, a fragile network of survivor zones has emerged. In Train to Busan 3: Redemption, the infection still lurks — evolving, spreading silently — and the world stands on the edge of a second collapse.

Haunted by his past and seeking absolution, Joon-seok (Gang Dong-won) returns from exile when a distress signal is traced to a quarantined train station deep in the heart of the Infected Zone. Among the trapped is Soo-an (Kim Su-an), now a young woman and one of the few immune to the virus. Her survival could hold the key to a cure — or unleash something far worse.

With time running out, Joon-seok joins a desperate rescue team aboard a fortified bullet train headed straight into hell. As the undead grow smarter and more coordinated, redemption will cost more than blood — it will demand sacrifice, courage, and confronting the monsters within.

Train to Busan: Redemption brings the gripping trilogy to a close with explosive action, emotional depth, and one final ride through fear, hope, and humanity.
