The Nightmare's life on earth is terrible. At least, that's what the insidious dictator cat himself thinks. People love him too much, they want to pet him every now and then and are always pestering him with their conversations. Well, who would like this?! But when the alien cat found out that a special agent dog had come from outer space to pick him up, he became seriously worried. The dogs from the interplanetary organization MOSKA want him to be punished for all his crimes. But Nightmare will never surrender to some flea-ridden dog! He will do everything to outwit him and not fall into his clutches. Even if this means asking people for protection and pretending to be a cute cat...
