A gruesome death. A sealed-off high school. Something crawling beneath the skin. When a student’s terrifying breakdown shocks a classroom, an almost invisible parasite spreads through the halls, instantly twisting teens into maniacs. Locked inside with no escape, students and staff spiral into violence and hysteria. Amid the chaos, Principal Van struggles to maintain control, drowning his anxiety in alcohol before losing his grip on reality – and his head. Burned-out science teacher Mr. Shanker steps up as the only adult trying to make sense of the madness, uncovering traces of a government experiment gone wrong. Outside the quarantined halls, Detective Sikorski races to contain the outbreak before it consumes the entire town. The real horror isn’t what’s under your skin – it’s what it makes you do.
