The tape takes us to a post-apocalyptic world in which a virus is spreading that has no cure and turns infected people into zombies. It does not do it immediately, but it takes a few months.
One of those infected is Maggie. She is a teenager who lives with her family on a farm in the United States, a secluded place where it is assumed that it is more complicated to become infected.
Despite this, Maggie is contagious, so her family has no choice but to see how the girl is transformed little by little, although they do not resign and will fight to stop the disease.
The one who fights the most is his father, since Maggie is his right eye. He is not resigned to seeing how his daughter becomes ill and becomes a danger to the rest of his family, so he will leave the skin to find a solution.
