12 girls, 12 boys, 1 abandoned city.
New vs. Old Generation.
Earth as we knew it vanished in 1990. Everyone died except the people who made it to the safe zone in Kansas, USA. Only about 100,000 people could fit in the safe zone, out of 5.1 billion people worldwide. With the fear of it happening again, males and females were separated and kids were forbidden to happen, but after years of trying to survive the people were growing old and needed new people to help, so the president made a requirement that only 24 kids shall be born in the month of December. After that they waited a few years to see if anything were to happen, since nothing happened they then started beginning their new world. They start with the safe zone and building the president's place on top of it, then dividing their open desert into 4 cities: Clementine, Morado, Beryl, and Hollow.
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.
