When a series of unprecedented solar superstorms strikes Earth, the power grid collapses—and so does civilization. For NOAA scientist Carson Carlisle, it’s a nightmare realized. He saw it coming, just not in time.

In Washington, D.C., his sister Willow navigates a city unraveling into chaos, desperate to escape and reconnect with her boyfriend, Knox, before it’s too late. Meanwhile, in Arkansas, their mother, Bee, a fiercely independent retiree, refuses to flee. As fear fractures her small community, she emerges as an unexpected anchor in the storm.

Scattered by distance and consumed by uncertainty, each must face rising threats, their own limits, and a world where the rules are gone. But even in the dark, their bond may be the one thing that still holds power.

When the Lights Go Out, the Fight for Survival Begins

Three days after a catastrophic solar superstorm cripples the nation’s power grid, America descends into chaos. With communications severed and no end to the upheaval in sight, the Carlisle family finds themselves separated by hundreds of miles—but united by one instinct: survival.

In Colorado, Carson and Julie are drawn into a desperate stand alongside a community on the edge. In Appalachia, Willow’s sudden entanglement with the law launches a dangerous journey across a fractured land. Back in Arkansas, their mother, Bee, clings to her community as panic spreads like wildfire. And in Dallas, their father, Arthur, arms himself to defend his home and his wife, Katherine.

Each must fight their own battle in a world without rules—where the strong decide who lives and dies.

Nearly a week after a catastrophic solar storm crippled the grid, Carson and his family, battered and exhausted, are scattered and face still more unknown dangers.

Carson presses forward, eyes fixed on Dallas, where he knows greater threats await. The journey ahead is dangerous, but he fears what’s ahead, maybe even worse.

Meanwhile, Willow believes she’s finally found a place to rest but her relief is short-lived, as she’s pulled into a nightmare darker than anything she’s faced before.

In Dallas, Arthur’s battle for survival reaches a critical tipping point, forcing him to make impossible choices.

And in Arkansas, Bee is no longer standing her ground. She’s on the run, with danger closing in from every direction.

As the country fractures and chaos reigns, the Carlise family will be pushed to their limits.

 Not all of them will make it through what comes next.
