THE LAST MARINE– Series SynopsisThe world ends not with a bang, but with a prayer and a shattered test tube. Marine Quinn Calloway, a man accustomed to the structured chaos of war, finds himself on leave in the deceptively peaceful mid-sized city of New Havenburg when the unthinkable happens. Dr. Lucian Kael, a brilliant and devoutly religious scientist at the prestigious Blackwood Research Institute, driven by a fervent desire to unlock humanity's “divine potential,” makes a catastrophic miscalculation.
