Jan Pančur and the Secret of the Invisible Gang

An entirely ordinary schoolboy, Jan Pančur, has already saved the world twice, but it seems his work is far from over. This time, he must save his father, who has been accused of robbing banks. He teams up with his homeroom teacher, who is actually from outer space; the school janitor, who is in fact a werewolf; and a lizard who turns out to be the ruler of a distant planet. Together, they set out to uncover a cunning plan, while the not-so-bright Inspector Flajs proves to be of little help.
