In a world untouched by chaos, two brilliant scientists—Ethan and Lena—find love amid their groundbreaking research to cure terminal diseases. But when a miscalculated experiment infects Ethan with a mysterious virus, their lives shatter. In an effort to protect Lena, Ethan secretly tests the serum on himself, only to trigger an unstoppable outbreak that turns humans into emotionless predators.
As the virus spreads like wildfire, Lena returns to a blood-stained lab, only to discover the truth: Ethan is the source. While the world descends into horror, Lena refuses to abandon the man she loves, convinced he still clings to his emotions. With heartache, guilt, and unwavering devotion driving her, she embarks on a harrowing journey—facing death, forging unlikely alliances, and fighting for survival—hoping to save Ethan, and perhaps the remnants of humanity.
But love may not be enough when the world falls apart, and the man she once knew becomes the monster everyone fears.
