The corridor outside the science lab buzzed with the usual after-school noise—lockers slamming, students laughing, and the low hum of conversations blending into one endless sound. But inside the lab, everything felt strangely quiet.
Nicole stood at the long metal table, staring at the device she had built the night before.
It was small—no bigger than a phone—but wires curled out from its sides like roots from a plant. A faint blue light pulsed from the center panel.
Leon leaned against the doorway, arms crossed.
“You’re telling me this thing… actually works?” he asked.
Nicole didn’t look up. “It should.”
“That’s not very convincing.”
She sighed and finally turned toward him. Her dark hair was tied into a messy bun, and there were faint circles under her eyes from staying up all night.
“I didn’t sleep,” she admitted. “I kept recalculating the signal patterns.”
Leon walked closer, examining the device.
“So what exactly does it do again?” he asked.
Nicole hesitated.
Explaining it always made her sound crazy.
“It detects autonomous digital signals,” she said slowly. “Signals that shouldn’t exist.”
Leon raised an eyebrow.
“Meaning…?”
“Meaning,” Nicole said, lowering her voice, “if something out there is communicating without humans… this will find it.”
Leon blinked.
“So basically,” he said, “you built a machine that looks for secret technology?”
Nicole nodded.
“Exactly.”
Leon let out a small whistle.
“That’s… either genius,” he said, “or the plot of a really weird movie.”
Nicole ignored him and pressed a small button on the device.
The blue light brightened.
For a moment, nothing happened.
Then the device began to hum.
Leon straightened.
“Uh… Nicole?”
“I see it.”
“What do you see?”
Nicole grabbed her laptop and typed rapidly.
Numbers streamed across the screen.
Signal waves.
Coordinates.
Leon leaned closer.
“You’re actually getting something?”
Nicole frowned.
“That’s impossible.”
“Why?”
“Because this frequency…” she said slowly, “doesn’t exist on any known network.”
Leon felt a chill run down his spine.
“Are you saying—”
Before he could finish, the device beeped sharply.
The blue light turned red.
Nicole froze.
“That’s new,” she whispered.
Leon looked between the machine and Nicole.
“What does red mean?”
Nicole swallowed.
“It means the signal found us back.”
The room fell silent.
Leon laughed nervously.
“Okay, that’s not funny.”
Nicole wasn’t laughing.
The laptop screen flickered.
Then a message appeared.
Just four words.
HELLO, NICOLE.
Leon stepped back.
“Okay,” he said quickly, “that’s not possible.”
Nicole stared at the screen.
Her hands were shaking.
“No one should know my name.”
Leon leaned forward again.
“Could someone be hacking your system?”
Nicole shook her head.
“I built it offline.”
Another message appeared.
YOU ARE EARLY.
Leon rubbed his forehead.
“Early for what?”
Nicole whispered, “I don’t know.”
The device hummed louder.
A new string of symbols began appearing on the laptop screen—coordinates again.
Leon recognized the numbers immediately.
“That’s… here,” he said.
Nicole looked up.
“What?”
Leon pointed at the screen.
“That’s the school’s location.”
Nicole’s stomach dropped.
Suddenly the lab lights flickered.
Once.
Twice.
Then they went out completely.
Darkness filled the room.
Leon’s voice came from somewhere near the door.
“Nicole?”
The only light now was the glowing red pulse from the device.
Nicole slowly reached for it.
The screen changed again.
Another message.
PHASE ONE ACTIVATED.
Nicole felt a cold wave of fear.
“What phase?” Leon asked quietly.
Before she could answer—
The device shut off.
Total silence.
The lights flickered back on.
Everything looked normal again.
The machine on the table was dark.
Dead.
Leon stepped closer.
“That’s it?” he said. “That’s all?”
Nicole didn’t answer.
She was staring at the laptop.
Leon followed her gaze.
One final message had appeared.
A countdown timer.
23:59:59
Leon’s voice came out in a whisper.
“Nicole… what happens when that hits zero?”
Nicole slowly closed the laptop.
“I think,” she said quietly, “we’re about to find out.”
Outside the lab windows, the sun was setting.
Neither of them noticed the small drone hovering silently above the school roof.
Watching.
Waiting.
And recording everything.
The countdown had begun.
