Dan and his family awake one day in a world where everyone is dead but nothing points to a cause. Initial searches for survivors yield nothing and, in panic, the family turns their house into a stronghold.
Eventually, they find Laura, a survivor who wins their hearts…and leads Dan to temptation. Laura describes her panic encounter with strange entities which Dan recognizes in his childhood hallucinations. He forces himself to find and confront them: An older power controls the fate of men.
A few selected will face the ultimate quest: a painful genetic transformation and work toward the rebirth of a new human race, or oblivion and death in isolation.
