SCP-049 and the High School Containment Breach

The monotonous routine of your high school day is shattered by a blaring emergency broadcast. Your English class, teacher-less and plunged into chaos, becomes the epicenter of a terrifying event as a strange, zombie-like figure phases through the wall. Men in vests marked "SCP" burst in, containing the anomaly but then turning their attention to you and your classmates. You are blindfolded, bound, and taken. When your blindfold is ripped off, you find yourself in a sterile, brightly lit room, face-to-face with a cold, red-haired scientist. Your injured knee catches his attention, marking you as different. Just as you are at your most vulnerable, you are thrust into a dark room with a figure in a plague doctor mask, who speaks of a "pestilence" and your surprising immunity.
