The year is 2217. All forms of expression and extracurricular activity are outlawed, as they are viewed as distractions to a productive lifestyle. Anyone who violates this law is subject to cleansing.
Cleansing is a process in which the faulty personality is placed in an isolation room for a duration no less than one hour in order to weaken the subject's mind. Then a more effecient personality is implanted into the subject, allowing them to return to benefit society.
This would never happen to you... Or has it?
