The Manning children cannot be more different.
The eldest, Xera, is a master in Kung Fu and a Majorette dancer. The middle child, Tony, is a computer genius who is close to starting his own company. And then there is the youngest, Theo. She's...exceptional.
As different as they are, they love each other and get along as normal siblings do. However, their once-peaceful world is snatched from them the moment their estranged aunt rides into town. The next thing these siblings know, their pets are talking and claiming that they are supposed to protect Sector 1969, AKA Earth.
Their world, or what they thought it was, will never be the same again.
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.
