Class Attendance: Meet the characters of Netflix’ All of Us are Dead

It’s the start of another weekend and if you’re looking for something to binge watch for the next couple of days, why not give in to the temptation and check out the most-talked about Netflix series All of Us Are Dead.

Homework, conflict with teachers, bullies and school crushes are all too common high school problems, but for the teens of Hyosan High School you can add ZOMBIE APOCALYPSE to their list of worries.

If you loved Kingdom or Train To Busan, All of Us are Dead brings the same thrills, scares and suspense–but at the same time bring you back to your high school days.

Trapped in a virus-ridden school with no cellphones, no food, and nobody to take care of them, the students reach for desk lamps, bookshelves, and bows to defend themselves from zombies in a desperate fight for survival. Want to know what to do and what not to do during a zombie apocalypse? Take a page out of Hyosan High school students’ book as they do absolutely everything they can to get out of their zombie-infested alma mater in All Of Us Are Dead.
