In the dead of night, a young couple, Polly and Seth, find themselves stranded on a desolate road deep in the woods after their car breaks down during a romantic camping trip. Their situation takes a terrifying turn when they're kidnapped by an escaped convict, Dennis, and his jittery girlfriend, Lacey, who are on the run from the law. Under the threat of violence, Polly and Seth are forced to navigate the tense dynamics of their captors while seeking an escape from their immediate predicament. As tensions between the four individuals mount, they all soon realize that their problems have only just begun.

The group seeks refuge in a deserted gas station, but they quickly discover they are not alone. A strange creature, harboring a deadly and infectious spore, is lurking in the shadows, marking the beginning of a nightmarish fight for survival. The entity exhibits horrific and rapid growth properties, infecting anything living in its path and turning them into grotesque versions of themselves. As they band together in an uneasy alliance, the odds of surviving the night grow slimmer by the minute, forcing them to put aside their differences and work together. Amid the chaos, the gas station becomes a claustrophobic battleground where human resilience is tested against a relentless and evolving threat.
