It's a race against time as the alien invading Syndicate continues their assault on our world. When all hope seems lost, the Space Marines uncover a secret in the form of a time capsule, a temporal totem that contains a message about how to fight back. Emboldened by the discovery, Quinn and the Marines begin hatching a plan to rebel by joining forces with the resistance, the very soldiers they’ve been forced to fight. Meanwhile, Quinn’s daughter has been stranded in the no-man’s land of vanquished cities littered with both friendly and enemy survivors of the invasion. She's forced to grow up quickly in the face of numerous life-or-death encounters, and soon links up with a ragtag group of guerrilla fighters to kick some serious alien butt. It’s not a matter of if mother and daughter's worlds will collide, but when … and once they do, the rebellion against the alien invaders will never be the same.
