Part 1: After Vecna

After Vecna, a strange plague falls upon the town of Hawkins, causing people to turn into walking corpses. Fortunately, even after losing contact with his friends, Eddie Munson creates a safe-haven at Hawkins High School for the new strange things happening in Hawkins for everyone he rescues. It wasn't long before he finds out that someone he has rescued was immune to the deadly disease that has spread throughout the town.

Eddie must decide on whether sacrifice this person to save everyone, or protect them from those who seek the blood of the immune.
