John leaves Sherlock alone for a second and may regret it forever.

Sherlock and John try to survive the end of the world as they know it. Separated from their group, their main focus is to survive and try to get as far North as they can. Unfortunate circumstances follow. Will this world be too much for them to survive?

When John wakes up from a coma in a post-apocalyptic world filled with zombies he is completely lost. That is, until he finds a stranger who seems to know all of the answers. Will John be able to survive this Hell with the help of genius Sherlock Holmes?
