CODE Z

The last few days from the last few people on earth.

Albert and Jesse has been stuck in there fortified home for too long.
As if limited resources and frequent power outages weren't enough, their 2 month old baby gets ill.
Just a few blocks from their home is the pharmacy.
And just a few feet from their doorstep is the undead.

( Being one of the most penned plots on sci-fi/horror genre, I have tried my max to keep it alive by backing it up with the most plausible zombie theories.)
