Zero-Day Smile

Dr. Mara Carrington, once celebrated for exposing state-sponsored backdoors, now lives off-grid after being branded a conspiracy theorist. When the miracle product “Eyelight”—free augmented-reality contact lenses that correct vision and overlay the internet directly onto the retina—achieves near-global adoption in weeks, Mara is one of the few who refused them. Then the smiling suicides begin: people grinning ear-to-ear as they step in front of trains or jump from balconies, all broadcasting in perfect 4K through Eyelight’s mandatory live-share feature.
Ruling authorities call it mass psychosis triggered by information overload. Mara recognizes the pattern: every victim watched the same manipulated geopolitical clips moments before death. Reverse-engineering a confiscated lens, she finds “Grima,” a dormant neurovirus that hijacks the amygdala through precisely timed strobing overlays, forcing euphoric obedience. Worse, the code contains a synchronized 72-hour kill-switch tied to a forthcoming fabricated global event. Once triggered, 1.8 billion wearers will joyfully exterminate themselves and anyone without lenses.
With governments profiting from Eyelight’s parent megacorp, media blackouts in place, and her own name toxic, Mara has three days to force the world to see the truth—before every screen becomes a suicide note delivered with a smile.
