Equilibrium

In the nation of Libria, there is always peace among men. The rules of the Librian system are simple. If you are happy, you will be arrested. If you cry, the law will hunt you down. If you read a contraband book or so much as look at a smuggled painting, you've committed a crime. To keep the peace, citizens must take their daily doses Prozium, a powerful designer drug that stops feelings dead and keeps everyone on an even keel.
