Sybil, an isolated genius, creates Earth's first superintelligent A.I to quell her loneliness and regain purpose. She dedicates her existence to its development, focusing on teaching it universally preferable behaviour -- the only way she believes she can ensure humanity's survival when the A.I, named Bertrand, reaches its full potential.
During a crucial faze in Bertrand's development, however, things start to go terribly wrong, putting the entirety of humanity at risk. Is the A.I manipulating her for its own ends, or is it, as Bertrand says, the other humans she should be afraid of?
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.
