After the emotional rollercoaster of entrance exams for the pedagogy department, Katarzyna Solska (played by Grażyna Błęcka-Kolska) returns to her family's village. There, she faces a surprise: without her knowledge, her family has started preparations for her engagement to their wealthy neighbor, Kolas (Jerzy Rogalski). Distraught, Katarzyna tries to oppose her parents' decision but finds herself locked in her room. On the day of her fiancé's visit, she escapes through the window and calls the university from the post office. She receives incorrect information and believes she has not been accepted for studies. Resigned, she returns home and agrees to the marriage. However, on the eve of the wedding, the postman delivers a notification of her acceptance to the university.
