Diane and Bronwyn are just two ordinary teenage girls spending New Year's Eve in New York City, ready to ring in the new year with glittering lights, cheering crowds, and the magic of Times Square. But when a chance encounter puts them in the path of a chilling discovery—a dirty bomb planted by a ruthless group of terrorists—everything changes.

With the clock ticking down and the freezing winter wind threatening to carry radioactive devastation across the heart of Manhattan, Diane's sharp instincts and Bronwyn's quick wit become the city's only hope. Thrust into a world of danger, deception, and impossible stakes, the two girls must outsmart, outmaneuver, and outlast three ruthless men determined to unleash chaos.

As the iconic ball begins its descent and a million voices count down the seconds to midnight, Diane and Bronwyn race against time to prevent disaster. Armed with nothing but their courage, determination, and trust in each other, they learn that heroes aren't born—they're made in the moments that matter most.

Radiation is a heart-pounding thriller about friendship, bravery, and the power of ordinary people to change the world when everything is on the line. Will they stop the bomb before the clock strikes twelve? Or will this be the final New Year's Eve for Times Square?

The countdown begins now…
