Hostages is about a high school that is struggling to survive an attack without any outside help. As Drew, a mute girl, fights the attackers with several other students, she notices that the attackers seem to have a keen interest in her. As they fight to keep Drew safe from the attackers while staying on the front line, she develops a skill that helps her in her battle, and surprisingly, the attackers know of it too. Drew believes that she developed the skill to help her free the students, but she begins to think that this might not be the big picture; there might be an even bigger picture hiding just out of view.
