A class of thirty-two high school students receive texts commanding them to complete strange tasks. Do what the messages say, and more will follow.

But until penalties for failure become lethal, no one is ready to step out of their comfort zone. With death around every corner, and as orders and punishments become more and more gruesome, the worst in people manages to tear its way out.
