Radioflash is a 2019 American disaster film directed by Ben McPherson. The story follows the aftermath of a devastating nuclear attack that causes an electromagnetic pulse (EMP) that cuts off all power, water, and communication to the entire western United States. Reese, played by Brighton Sharbino, is a teenage girl who must fight to survive in a world gone mad where every encounter with a stranger could be her last.
After the EMP hits, Reese and her father, Chris, played by Dominic Monaghan, set out on a dangerous journey to find safety. Along the way, they encounter a group of survivors who have banded together for protection, but the group's leader, Mason, played by Will Patton, insists that anyone who wants to join them must prove their worth.
Reese struggles to keep up with the group's demands and her father's failing health, all while trying to maintain hope for the future. As they journey farther into the chaos, they encounter not only violent gangs but also unexpected allies who may be their only hope for survival.
The film combines the familiar tropes of post-apocalyptic survival thrillers, such as limited resources, harsh landscapes, and dangerous enemies, with an exploration of family bonds and the power of hope.
