Welcome to the world of after strike, a ravaged planet hit by numerous meteor strikes after a larger asteroid is broken into smaller chunks by orbiting nuke platforms (guess all those top secret communication satellites launches weren't just satellites) which then blankets the earth in a huge dust cloud, luckily it dissipates quickly and we're spared a extinction level event but when all is said and done about two thirds of the earth's population is killed. The total disruption of commerce, utilities, and services only further exacerbated the problems for the survivors. That was the good news, the bad news was about three or four days later the dead decided that they didn't want to stay dead and started to wake up, the really bad news was that when they woke up, they work up hungry and thought that warm human flesh was the next best thing since sliced bread. Enter Jack Trotta former Force Recon marine scout/sniper. Trained to live off the land and survive under the harshest of conditions he meets the last hope for the salvation of the remaining human race in the most unlikely of places, twin brothers whose blood contain the serum that can stop the virus that has infected every human on the face of the planet by the cloud . Jack must get these two kids to the CDC in Atlanta on a 450 mile trip through a lethal and violent land were the zombies might turn out to be the least of his problems and your first mistake will likely be your last. Faced with psychotic human cannibals and other miscreants who have reverted back to the law of the jungle and survival of the fittest that arduous journey is further complicated by being forced by God (who has lost faith in humanity) to accomplish it on foot. Informed by his dead wife who is sent as a messenger in the form of a shimmering aberration that God had intended for the asteroid to wipe out mankind and start over and that the last chance for the survival of the human race is the two young boys who hold the cure. Tasked with such an overwhelming responsibility thus begins the most important mission he has ever undertaken with the specter of failure not an option.
