Kyungmin, who’s pride had hit rock bottom being bullied by his friends, somehow gets invited to a group chat named “Deathcord” in which you can vote to kill someone. It was so sudden. In the group chat, the members are all anonymous in which each individual can vote for one’s execution! Every one of the anonymous participants have their own reasons to kill someone. Then, the individuals in the group chat move to identify each other, after one of the individuals in the chatroom gets voted to be executed but… The game that will never end unless they kill each other, begins!
