A sudden and inexplicable blackout blankets Detroit, and when the lights return, the city's population has mysteriously vanished, leaving only piles of empty clothing and deserted streets. In the days that follow, a small group of disparate individuals discovers each other. Among them are a television reporter, a physical therapist, a theater projectionist, and a young boy. They quickly realize that the darkness is not merely an absence of light but a malevolent force that consumes anyone who lingers in the shadows. Battling against their primal fears and the encroaching darkness, they seek refuge in a dimly lit bar that somehow remains illuminated by a flickering generator.

Amidst dwindling resources and growing paranoia, they struggle to maintain hope and sanity while trying to unravel the mystery of the disappearing populace. Their predicament is compounded by the realization that the darkness is sentient and actively hunting them, exploiting their weaknesses and deep-seated fears. As the power in the bar wanes and their temporary sanctuary becomes increasingly perilous, they are forced to confront their growing desperation and look for answers that could lead to salvation—or their ultimate doom. Their harrowing journey through an abandoned cityscape forms the nerve-wracking backdrop for a relentless fight for survival.
