The movie opens with Sirona locked in a lab, being experimented upon by the scientists at Valkyrie. We see her undergoing painful procedures, being injected with various substances and being electrocuted. However, Sirona is not just any ordinary human. She has unique abilities that the scientists are trying to understand, which include enhanced strength, speed, and agility, along with the ability to control and manipulate electronic devices through a mental link. As the experiments progress, Sirona becomes more and more restless, feeling trapped in her prison.
One day, during an experiment gone wrong, Sirona finally escapes. The scientists at Valkyrie panic and alert their bosses, who decide to cover up the incident and send a team of mercenaries to retrieve her. Meanwhile, Sirona roams the Rocky Mountains, trying to find her place in the world and control her powers. She discovers that she is not alone, and there are others like her who have escaped from Valkyrie, but they are all being hunted by the mercenaries.
Enter Allen Cross, a veteran mercenary and leader of the team tasked with capturing Sirona. He is a no-nonsense type of guy, who follows orders to the letter and is willing to do whatever it takes to complete a mission. On the other hand, Cross also has a conscience and sympathizes with Sirona's plight, having seen first-hand the horrors that Valkyrie is capable of.
As the chase and cat-and-mouse game between Sirona and the mercenaries intensifies, Cross finds himself torn between his duty and his morals. He starts to question the motives of his employers and realizes that the mission is not what it seems. In the end, Cross decides to help Sirona and the other escaped experiments, leading to a final showdown with the remaining mercenaries and the powerful force behind Valkyrie. The movie ends with Sirona and Cross going their separate ways, but with a promise to work together if they are ever needed again.
