Months after the zombie outbreak that decimated the world's population, Rose, Dakota, Erik and Ian embark on a routine supply run only for it to end in disaster. Ian is killed instantly. Erik, meanwhile, is scratched.
Unaware if such a wound will leave their companion helpless to the zombie virus, the party waits to see if Erik will succumb to infection. When he doesn't, it seems too good to be true. But Erik isn't out of the woods yet. With fever symptoms leaving him bedridden, it's obvious that he's going downhill—and fast. And only a chance communications with an infectious disease specialist in the capital offers their only chance of hope.
