The suburban school is totally bankrupt. When all hope collapses, Makkosi, a teacher resigned to the disappointing situation, and Annamari, a pretty French teacher, end up in a casino in Szentendre. They are surprised to discover that Makkosi can predict the winning numbers at roulette. The maths teacher is unimpressed and when her love seems to be on the wane, she puts all her eggs in one basket: to save her life, her love and her school. His mad plan is to multiply the school's meagre funds in the Monte Carlo casino.
