The light died and darkness descended. For technician Josie and her team, the sudden collapse of the Lightspeed wireless grid was more than just the end of a job- it was the beginning of a terrifying nightmare. Stranded, abandoned, and under siege at one of Lightspeed's aid centers, their only chance at safety is a perilous trek to a nearby community they hope will offer refuge. In the rugged mountains of Virginia, Jim Powell leads a hardscrabble community clinging to survival. They've carved a life out of the ruins, restoring safety and a sense of purpose, but they've also endured violence, devastating loss, and crushing despair. When Josie's team shows up, they bring a terrifying truth: America's collapse has created a vacuum, and powerful, ruthless players are moving in. Now, Jim, a reluctant leader who never wanted the job, must make a choice that will define the fate of his community: fight alone against overwhelming odds, or make a perilous alliance with a steep and uncertain price.
