Hanna from Újvári lived the usual life of a teenager until a year ago, but a family tragedy changed everything. Now he spends his weekdays alone with his father, and he is no longer concerned with the average problems of his age group.
After receiving his eleventh grade certificate, after the end of the year he receives an unexpected invitation from the principal: he can participate in a school competition where, as an excellent mathematician, he is mainly expected to solve logical problems.
Hanna's environment insists that she go to the competition, so the four-person team from Szirtes High School starts the National Competition of Schools.
