The Lockdown was (obviously) a lockdown. Instead of being ran by the faculty, it was ran by Emette. It took place after a science class. Emette boarded up all the exits and smashed the lockers, which are still not replaced. The trapped students, led by Kat, looked for various ways out, while the faculty did nothing. They got out the very next day. It was revieled later that the scheme was actually Sherry's idea.
