On that fateful day, 16-year-old Norman was sipping his usual iced tea before school. But this time, along with his tea, he had something completely unusual and magical: three microscopic aliens and their entire spaceship!

The aliens, sent to Earth by the evil space lord Zoltard, get used to their new surroundings - Norman's brain - and decide to make contact with the boy. At first, Norman of course thinks he's lost his mind a little, but he gradually makes friends with the strange space friends in his head.

The games will have to wait: it turns out that Zoltard has also taken over the brain of the school's headmaster. His goal is to take over the school, and then the whole Earth! With the help of Norman and his friends, the little brain inhabitants will have to use all their wisdom, skills and courage to stop the headmistress and Zoltard.
