The zombie apocalypse is over...
Now even undead kids have to go to school.
 
Morty Graves survived the apocalypse. Well, technically he didn't survive so much as get turned into a zombie. But when a vaccine stops the spread of the zombie virus, the world goes back to almost normal. Kid zombies kept their minds, unlike the adults. Morty's lawyer mother sued for him to have full human civil rights. Morty liked the idea in theory until he realized that meant he had to go back to school.
Now Morty will have to deal with fitting in among live kids without being able to speak, an assistant principal who has it out for him, a vicious bully, and kids who don't get his jokes.
 
It's going to be a long school year.
