Leo's ordinary existence derails when a supernatural phenomenon brands his vision, allowing him to perceive floating red numerals counting down the exact remaining hours for anyone facing imminent mortality. He dismisses the visions as hallucinations until a pedestrian marked with a zero is struck by a reckless truck right before his eyes. Terror takes hold when he boards a commercial flight and discovers identical red zeros hovering over every single passenger.
Desperate to prevent the catastrophe, Leo triggers a chaotic commotion to halt the departure, only to be tackled by security and ejected onto the tarmac. A single perceptive traveler named Anna trusts his sheer panic and disembarks beside him, watching in horror minutes later as the jetliner explodes on the horizon. Marked by death and hunted by authorities, Leo and Anna must navigate a world of ticking clocks.
