Plot Synopsis
Former Army sniper Celeste (Adria Arjona) has left the battlefield behind, dedicating her life to raising her young daughter in peace. But that quiet life is shattered when a classified military experiment goes horribly wrong.
After an army of genetically engineered super soldiers escapes from a top-secret government facility, the unstoppable killing machines begin leaving a trail of destruction in their wake.
With civilization rapidly collapsing, Celeste is forced to rely on her elite military training to protect her daughter against an enemy that is faster, stronger, and nearly impossible to stop.
As she uncovers the truth behind the secret program, Celeste realizes the terrifying outbreak is part of a much larger conspiracy. To survive, she must battle ruthless super soldiers, confront dangerous government secrets, and fight for humanity’s future before the unstoppable onslaught consumes everything in its path.
