Last season, the 2nd Mass found themselves under brutal attack by a new Espheni war machine - and a deadly new creation unlike anything previously encountered. Divided like chattel and spread to the winds, they forged new relationships and fought harder than ever to survive. As season five opens, all breed of beast and mutant are running rampant on earth. The Espheni's power core has been destroyed, and humans are now ready to fight on their terms - even if it means resorting to hand-to-hand combat against the enemy. After years of being tortured, imprisoned and mutated and having their loved ones stolen from them, Tom and the 2nd Mass are filled with rage, ready to destroy the enemy in an all-out battle to determine the fate of Earth. Witness mankind's final stand.
