It has been a year and a half since a tragic event took the lives of the children and the Sleeper virus cascaded out of control causing those infected to be more deadly than any disease. Life is divided as what's left of humanity struggles to divert extinction. Alex Sans leads a growing group of survivors who find sanctuary in a place they call Grace. It is a daily struggle to return to some sort of normalcy despite the dangerous world just outside their walls. They are succeeding, thriving and moving forward past their losses. Unfortunately, fate has dictated that man is not meant to survive 'The Event' and the Sleepers are to inherit the earth. Alex and the others face that reality as the Sleepers press closer to their gate and their semi-peaceful existence shatters. Sleepers 3 takes a surprising and dramatic turn as dark truths emerge, heroes rise to the occasion, and heartbreaking sacrifices are made.
