Trailer: Rehtori

Sari is a high school principal with high standards but no idea of what to do with them. In the teachers' lounge her nitpicky style hasn't won her popularity. When Sari hears that the teachers are organizing a get-together and she's not invented, she decides to act: get an invitation and win everyone's hearts. There is nothing standing in the way of her and popularity - except one broken mug.
