Protagonists

In every High school, you have different social cycles where each student belongs to. What would happen if 4 students from very different groups end up being a target by an unknown individual hiding in the shadows?

Will each one try to save him or herself? Or, will they stick together and try to solve this mystery as a team, only to find out that they are connected by more than just mere coincidences and incidents.
