Seoul, South Korea – 28 Hours After Outbreak
The infected toddler’s gnarled fingers clawed through the hanok’s paper door, its milky eyes fixed on Ji-eun. Behind it, Hyun-kyu’s mutated silhouette loomed, blue-veined pupils glowing like bioluminescent poison. “You can’t hide,” he rasped, his voice a guttural blend of human malice and something other.
Min-jun hurled a wooden bench against the door, but the toddler squirmed through the tear, jaws snapping. Jin swung his baseball bat, caving in the creature’s skull with a sickening crunch. “Stay back!” the teen shouted, but the horde outside echoed Hyun-kyu’s laughter—a chorus of wet, rattling screams.
Ji-eun slumped against a support beam, her breath shallow. Sweat dripped down her neck, her pulse thundering in her ears. Not yet, she begged silently. Not yet.
The Defense
The hanok’s courtyard became a battleground. Min-jun and Jin barricaded the main hall with overturned furniture while the surviving refugees—a hollow-eyed nurse and a taxi driver—dragged Ji-eun to the inner room. Outside, infected bodies piled against the walls, their moans syncing into a haunting rhythm.
“They’re herding us,” Min-jun realized, peering through a slit in the blinds. Hyun-kyu stood atop a car, directing the horde with jerky hand gestures. “He’s using them like pawns.”
Ji-eun’s fingers trembled as she scribbled on a scrap of wallpaper: Prion clusters in brainstem → hive communication? Her vision blurred. “W-we need to… disrupt his signal,” she stammered.
“How?” Jin snapped. “Asking nicely?”
A crash echoed as the hanok’s east wall collapsed. The infected poured in.
Flashback: Two Days Before Outbreak
Ji-eun stood in her lab, staring at the biohazard bin. Inside, a lab rat twitched, veins blackening. Her colleague, Dr. Park, adjusted his goggles. “The prion’s adapting to living tissue. It’s learning.”
“Destroy it,” Ji-eun ordered.
Dr. Park hesitated. “What if it’s the only sample left?”
She incinerated it herself.
Now
Min-jun grabbed a ceremonial sword from the hanok’s ancestral shrine, slicing through infected limbs. “Ji-eun! The cure—now!”
She fumbled with her medkit, drawing her own blood into a vial. “My T-cells… might neutralize the prion,” she panted. “But I need a lab to replicate them.”
The taxi driver screamed as an infected child sank teeth into his calf. The nurse dragged him back, tying a tourniquet. “We’re out of time!”
Hyun-kyu’s clawed hand smashed through a window. “Join us,” he crooned, his words slithering into Ji-eun’s fevered mind. “No more pain. No more lies.”
She gripped the vial. I’m lying to them. I’m lying to myself.
The Choice
Min-jun hauled her into the courtyard’s koi pond, the stagnant water hiding them waist-deep. Hyun-kyu’s horde circled, snarling but hesitant. “Water disrupts their scent?” Min-jun guessed.
Ji-eun shook her head. “They’re waiting for orders.” She pressed the blood vial into his hand. Her skin was gray. “If I turn… inject this. It might buy you minutes.”
“No.” He cupped her face. “You’re not dying in a pond.”
“I’d prefer a beach,” she joked weakly.
Their lips met—a salty, desperate kiss. Above them, the moon vanished behind smoke.
The Signal
Hyun-kyu howled, and the horde attacked. Jin and the nurse fell back to the shrine, swinging a censer of smoldering incense. The infected recoiled—fire? No. Sandalwood.
“The prion hates strong scents!” Ji-eun coughed. “Disrupts neural pathways!”
Min-jun tossed Jin a perfume bottle from the rubble. “Aim for the eyes!”
Hyun-kyu roared, charging through the pond. Min-jun raised the sword—
Crack.
A sniper bullet tore through Hyun-kyu’s skull. His body spasmed, the horde freezing mid-lunge.
On the hanok’s roof stood a woman in a tattered lab coat, rifle smoking. Dr. Park.
“Miss me?” he called.
The Escape
Dr. Park led them through a sewer tunnel, his flashlight revealing graffiti: THE CURE IS A LIE. “The military’s rounding up survivors,” he said. “But I know a place. Underground lab. Never decommissioned.”
Ji-eun stumbled, her pupils flickering black. “How… did you find us?”
Dr. Park glanced at Min-jun. “Tracked your vitals. Your smartwatch.” He paused. “Also, you forwarded my research to 300 people. Thanks for that.”
The group emerged near Namsan Tower, now a jagged ruin. Below, the Han River glittered with floating bodies.
“The lab’s in Bukhansan Mountain,” Dr. Park said. “We go north.”
Ji-eun collapsed. Min-jun caught her, feeling her fever scorch his arms.
“Don’t let me turn,” she whispered.
Dr. Park frowned. “Too late. Look.”
Her veins pulsed faintly blue.
End of Episode 3
Next episode teaser: As the group races to Bukhansan, Ji-eun begins to mutate—gaining terrifying abilities that blur the line between human and monster. But Hyun-kyu’s hive mind isn’t truly dead… and it wants her back.
