In the year 2057, the Atomic World War began. It started with the newly elected United States President getting assassinated and ended with the world in ash, destroyed by it's own inhabitants. All the humans that had survived, around 550,000, had been put into bunkers, where they stayed for the next 21 years. Once the nuclear winter the bombs had cause had lightened up, many bunkers began colonizing the Old World. Due to the still freezing temperatures, they were forced to construct complex domes around their cities, allowing them to grow their own food. But from the crumbled remains of the previous government rose a new one, more power hungry and dangerous than the last. The former vice president seized power and ran the Bubble City as a dictator, kidnapping lower level citizens and experimenting on them to create super soldiers. One of the first successful subjects escaped though, finding her way to a old, sad, man, living alone in the Old World. Will they be able to find peace together or will the vengeful government come for them both.
Season 4 of The Virus Within
Trinity is familiar with zombies, being one herself, but when strange zombies start appearing, she realizes that the world she knew might be changing yet again.
When a dangerous set of scientific notes are discovered, Trinity and her friends don't realize anything is wrong until a frantic radio call comes in. Unaware of the notes, they race to the south and struggle to determine where the strange zombies came from. The zombies are unlike any ranks previously seen, and they aren't as predictable. Some have new tricks hidden up sleeves, forcing any Stronghold they encounter to quickly adapt to the new challenge or risk being overrun. Secrets never remain hidden, and zombie apocalypses never make life easy.
