The teaser trailer for Train to Busan 3: Unveiling Peninsula opens with a chilling scene of a dense, fog-covered city skyline.

The camera sweeps over the desolate ruins of what was once a thriving metropolis, now eerily silent, with smoke still rising from the remains of collapsed buildings and overturned cars. Faint sounds of distant screams and moans echo through the empty streets, hinting at the horror that still lingers.

A haunting piano melody begins to play as the camera moves toward a heavily fortified quarantine zone at the city’s edge. The atmosphere is thick with tension as a voiceover from an unseen survivor begins, “We thought we had escaped… but the infection knows no boundaries.”

Cut to a series of quick flashes: survivors hiding in the shadows, faces filled with fear; a group of refugees huddled together in makeshift camps; and military convoys moving through devastated landscapes, their occupants scanning the area for threats. A new protagonist emerges, a former soldier (played by a prominent actor), who is leading a team of scavengers through the dangerous peninsula, now a zombie-infested wasteland.

The trailer reveals that the infected have evolved — they’re faster, smarter, and more coordinated than ever before. A horrifying scene shows a horde of zombies moving in unison, navigating obstacles with terrifying precision, and swarming like a force of nature. “This isn’t like before,” the protagonist whispers, staring into the distance. “They’ve learned.”
