A long time ago, in a galaxy far, far away, residents of a small planet began to lose the power to feel and experience emotions. In order to find the solution to this problem an expedition was sent out in outer space, which one day discovered planet Earth. The gift of the empath girls that were found there was harnessed to start making emotion-gathering amulets. In turn, emotions that were harvested by those amulets were made into candy called "Secrets" - a drug that temporarily returned the consumers emotions. But soon after, the government affected by the loss of emotions started a campaign for the perfect community, which main purpose was to opress those who still had feelings. A revolution was started by a few brave ones. And to bring the battle to a close, officials introduced a special device, that affected candy consumers in a certain way. But they are forgetting that rebels also have something up their sleeve.
A little side-note: Creatures with button-like eyes don't have emotions.
