Isabel Leon, the star of a survival reality show, thinks she can endure anything. But when she unwittingly gives an unscrupulous mogul a chance to profit from her murder, she becomes the target of a terrifying killer who makes nature seem tame by comparison.
At first left for dead, she is rescued by a medical research team that operates outside the law. She awakens to find she's the living proof of a breakthrough that can change the world. Some people would pay any price to control it. Others would simply steal the secret—even if it costs Isabel's life. As powerful rivals pursue her, Isabel must risk everything to protect those she loves—or die again tomorrow.
