INT. SERVICE TUNNELS - DARKNESS - CONTINUOUS
The emergency lights came back on after thirty seconds.
They’d moved through the darkness by feel, hands on shoulders, breathing synchronized, the sounds of pursuit growing closer with every step. Now, in the sickly green glow, John could see what had been chasing them.
Three infected. Different from the others. Fresher. Their transformations incomplete, clothes still recognizable as resort uniforms. They moved with terrible speed, rabies-driven aggression barely contained by bodies that hadn’t finished dying.
“SERVICE ELEVATOR,” Diego shouted. “TWENTY METERS!”
John shoved Michael toward the elevator doors. “GO! I’ll hold them!”
“Dad, no…”
“I said GO!”
Lisa grabbed both kids, pulling them toward the elevator with strength born of pure terror. Diego slammed the call button, muttering prayers in rapid Spanish.
John turned to face the infected.
He had no weapon. No plan. Just twenty years of studying disease, of understanding how pathogens worked, how infected bodies moved, what they could and couldn’t do.
The first one reached him. John sidestepped, grabbed its arm, used its own momentum to send it crashing into the concrete wall. Dazed, not dead. The infection was making them more resilient.
The second came faster. John took a hit to the shoulder that spun him around, stars exploding behind his eyes. But he kept moving. Kept dodging. Kept buying seconds.
“ELEVATOR’S HERE!” Lisa’s voice, cutting through the chaos.
John ran. The third infected caught his ankle, sent him sprawling. He kicked. Once. Twice. Three times. Felt cartilage crunch. The grip released.
Then hands were grabbing him. Human hands, pulling him into the elevator as the doors slid closed inches from the infected’s snapping teeth.
INT. SERVICE ELEVATOR - CONTINUOUS
Heavy breathing. The mechanical hum of descent.
“Is everyone okay?” Lisa was already checking for injuries, her hands moving with practiced efficiency. “John, your shoulder…”
“Fine. Bruised, not broken.” John leaned against the elevator wall, letting the adrenaline fade. “How far down does this thing go?”
“Research level,” Diego said. “Below the main facility. This is where they do the real work.”
“And from there?”
“Maintenance stairs to the surface. We come up near the marina’s storage building.” Diego’s face was grim. “But we will have to pass through the lab.”
“The lab where the outbreak started?”
“Yes.”
John closed his eyes. Of course it would be through the lab.
“Do you know what’s down there?” Lisa asked. “What we’ll be walking into?”
“Only what I’ve heard.” Diego crossed himself. “They call it Ground Zero. The workers, we were never allowed near it. But the stories…” He shook his head. “They said people went in and didn’t come out. Or came out changed.”
“Changed how?”
Before Diego could answer, the elevator jerked to a stop. The doors slid open onto a corridor that made the wellness center look welcoming.
Concrete walls. Flickering lights. The hum of containment systems running on backup power. And that smell. Antiseptic over decay. Stronger here than anywhere else in the resort.
“Everyone stay close,” John said. “We move fast, we stay quiet, we don’t stop for anything.”
They stepped into the darkness.
INT. RESEARCH LEVEL - CORRIDOR - CONTINUOUS
The corridor stretched ahead. Biohazard warnings marked every door, their orange symbols glowing in the emergency lighting. John led. Lisa brought up the rear. Kids and Diego sandwiched between.
“This place is massive,” Sarah whispered. “How did nobody know this was here?”
“Money.” John’s voice was bitter. “Enough money can hide anything. Shell companies, private islands, resort fronts. They built an entire bioweapons facility under a vacation destination and nobody asked questions.”
“Why here though? Why not somewhere less populated?”
“Test subjects.” Diego’s voice was hollow. “Wealthy guests from all over the world. Different genetic backgrounds. Perfect for testing how the virus affects different populations.”
The implications were too horrible to acknowledge directly.
“Through here.” John pointed to a door marked LABORATORY A - PRIMARY RESEARCH. “According to the maps I saw, the maintenance stairs are on the other side.”
He pushed through. And stopped.
INT. LABORATORY A - CONTINUOUS
The lab was a cathedral of horror.
Rows of containment chambers, each one holding a specimen in various stages of transformation. Some were barely infected. Fever stage. Hemorrhaging just beginning. Others were far gone, their bodies twisted and gray, the fungal component visibly growing beneath their skin.
And some were perfect. Fully transformed. Standing motionless in their chambers, filmed eyes tracking the movement of the newcomers with predatory intelligence.
“They’re dormant,” John breathed. “The infection has a dormancy state. They’re conserving energy until prey is available.”
“Then we need to not be prey.” Sarah pulled Michael closer. “Which way?”
John scanned the lab. The maintenance door should be at the far end, past dozens of containment chambers, past equipment he didn’t want to examine too closely.
“There.” He pointed. “Emergency exit. Fifty meters.”
“And the things in the chambers?”
“Containment should hold.” John didn’t add the should. Didn’t add that he’d seen what happened when containment failed.
They moved. Every step measured. Every breath controlled. The dormant infected tracked them, heads turning in their chambers, but the glass held. The locks held.
They were halfway across when Lisa stopped.
“John.” Her voice was strange. “Look at this.”
She was staring at one of the containment chambers. Not at the infected inside, but at the data readout on the exterior. John followed her gaze.
Subject 47. Female. Age: 34. Infection Status: Stage 3 Complete.
Notes: Exceptional response to treatment protocol. Neural pathway modification successful. Recommend for Phase 2 deployment.
“Deployment,” Lisa whispered. “They’re not just making these things. They’re programming them.”
“Weapons.” John’s voice was numb. “They’re creating weapons.”
“Dad.” Michael’s voice, urgent. “Dad, we need to move.”
“What…”
Then John saw it. The containment chamber Michael was pointing at. Subject 89. Male.
The door was open.
INT. LABORATORY A - CONTINUOUS
The infected emerged from between two equipment racks. Stage 3. Fully transformed. But different from the others. Faster. More controlled. The product of whatever “Phase 2 deployment” meant.
It locked onto Lisa.
What happened next occurred in fragments:
Lisa raising her knife. Too small. Too slow.
Diego lunging forward, his kitchen blade finding the infected’s side.
The infected spinning, grabbing Diego by the throat.
Michael screaming, throwing a beaker heavy with chemicals.
The infected dropping Diego, turning toward the new threat.
And Lisa. Lisa the nurse. Lisa who’d spent twenty years saving lives. Finding that everything she’d learned about anatomy, about vulnerable points, about how to keep people alive could be reversed.
Her knife took the infected through the eye. Deep. Final.
The creature dropped.
Lisa stood over it, breathing hard, covered in blood that wasn’t hers. Her face held an expression John had never seen before.
“We need to move,” she said. Her voice was steady. “Now.”
INT. LABORATORY A - EXIT CORRIDOR - CONTINUOUS
They ran.
The commotion had woken the dormant infected. John could hear them stirring in their chambers, pressing against glass that was never meant to contain them long-term. Time was running out.
“Door’s ahead!” Sarah had taken point, leading the family through the maze of equipment and horror.
“It’s locked!” Michael reached the exit first, yanking at the handle. “Keycard access!”
“Move.” John pulled out the card he’d taken from Mark Watney. Please work.
The light flashed green. The door opened.
Behind them, glass shattered. The dormant weren’t dormant anymore.
“GO GO GO…”
They poured through the door. John slammed it behind them, heard the lock engage, felt the vibration as infected bodies crashed against the other side.
“Stairs.” Diego pointed. “Two flights up, door on the left. That’s the marina access.”
They climbed.
INT. MAINTENANCE STAIRWELL - CONTINUOUS
The stairs felt endless. John’s legs burned. His shoulder throbbed. His lungs screamed for air. But stopping wasn’t an option.
“Almost there,” Diego gasped. “One more flight…”
The door above them burst open.
Not infected. People. Resort security, dressed in tactical gear, weapons raised. Elena’s voice echoed down the stairwell:
“That’s far enough, Dr. Harrison.”
John stopped. Lisa stumbled into him, the kids behind her. They were trapped. Infected below. Guards above.
“You’ve caused quite a bit of trouble.” Elena descended the stairs, flanked by two guards. “Corporate is impressed. And concerned.”
“You’re murdering people. Hundreds of people.”
“We’re conducting a field trial. Admittedly, containment wasn’t as successful as projected, but the data we’re collecting is invaluable.” She smiled. “Your survival, Dr. Harrison, is a bonus. A CDC virologist who can testify to the efficacy of the product? Investors will pay a premium.”
“I won’t help you sell bioweapons.”
“You won’t have a choice.” Elena gestured to her guards. “Take them. The maintenance worker is expendable.”
The guard raised his weapon toward Diego.
Sarah moved.
Later, John would try to understand where his daughter had learned to fight. Student council didn’t teach that. Neither did the college prep classes she’d been taking. But Sarah was between Diego and the guard, her knife pressed against the guard’s throat.
“Drop it,” she said. Her voice was steady. Dangerous. “Or I find out how sharp this is.”
The guard’s weapon clattered to the stairs.
“Interesting.” Elena didn’t seem concerned. “The whole family has teeth. Perhaps we should keep you all.”
“Sarah.” John’s voice was careful. “We’re going to back away. Nobody needs to…”
The infected hit the door below them.
Metal screamed. Hinges gave way. The stairwell filled with the sound of things that used to be human, pouring up from the lab in a wave of hungry death.
“MOVE!” John grabbed Michael, shoved him past Elena, past the guards. Lisa and Sarah followed, Diego half-carried between them. Behind them, Elena was screaming orders. But her guards weren’t listening anymore. They were running too.
Everyone was running.
The infected didn’t care about uniforms or agendas or profit margins. They just cared about meat.
EXT. MARINA - STORAGE BUILDING - DAWN
They burst into sunlight.
The marina stretched ahead of them. Docks. Boats. The promise of escape. But between them and freedom stood a nightmare.
Infected. Dozens of them. Milling around the boats, drawn by instinct John didn’t understand. They turned as the survivors emerged, milky eyes fixing on living prey.
“The storage building.” Diego pointed to a structure at the end of the nearest dock. “There’s a speedboat inside. I saw them store it last week.”
“Can you drive it?”
“I can try.”
“That’s going to have to be good enough.” John looked at his family. Exhausted. Bloody. Terrified. But still standing. Still fighting. “When I say run, we run. Stay together. Nobody stops.”
Lisa took his hand. Sarah took Michael’s. Diego gripped his knife.
Behind them, the stairwell door exploded outward. The horde from the lab joined the horde from the marina.
“Run,” John said.
They ran toward the boats.
They ran toward whatever came next.
They ran, because that’s what Harrisons did.
Together.
