The Second Signal

The air in District 9 tasted like rust and recycled oxygen. At exactly 21:00, the broadcast crackled to life from the single speaker bolted to the ceiling of their cramped safe room. Chan's hand hovered over the radio dial, ready to kill the noise the moment the curfew message ended. The usual voice — flat, authoritative, monotone — began its nightly recitation: "Attention all residents. Curfew is now in effect. All citizens must remain indoors until the morning bell. Any unauthorized movement beyond this perimeter will be met with..." Felix had been in the middle of a joke, something about a rat that had gotten into the rations last week. Jisung was sprawled on the threadbare couch, half-listening, half-dozing. But when the broadcast hit the word "perimeter," Felix stopped. Mid-syllable. His head tilted, eyes unfocused, like he was trying to hear a whisper from a mile away. "Lix?" Chan's voice was low, careful. Felix didn't respond. His knuckles whitened where he gripped the edge of the table. The broadcast continued, but something was wrong. Underneath the official voice, there was a second layer — a crackling, distorted undertone that seemed to pulse in a rhythm not quite aligned with the announcement. It was faint, almost inaudible, but Felix's pupils dilated. His breath hitched. "I hear... something," Felix whispered. His voice trembled. "It's not Korean. It's... English. A man. He's saying — 'Is anyone there? Please. I'm trapped. Help me.'" Jisung sat up so fast his head nearly hit the low-hanging lamp. "Wait, what? The broadcast is only supposed to be the curfew." Chan's hand shot to the radio dial. He didn't twist it off. Instead, he yanked it toward him, turning the volume knob with a sharp, deliberate motion, as if he were pulling the pin on a grenade. The static surged, then flattened into a thin, eerie hum. The second voice became clearer — broken syllables, a man's voice, desperate and exhausted. It repeated the same plea in a loop. "That's not part of the system," Chan said, his jaw tight. "Someone's piggybacking on the tower's frequency. Which means either they're inside the wall, or..." He didn't finish the thought. Felix's eyes met his. "Or they're outside." Outside the wall was the dead zone. The place no one came back from. The place the broadcast said was empty, poisoned, erased. But the voice on the radio was real. It was human. And it was begging. Jisung was already reaching for the notepad they used for code-breaking. "We need to record this. If there's a pattern, I can find it." Chan let go of the dial, his hand shaking slightly. The broadcast was supposed to be safety. The curfew was supposed to be the only danger. Now he realized: the walls weren't just keeping them in. They were keeping something out. Or maybe, something in.
