Zofie and Dominika, two girls of very different temperaments, become friends during hop-picking volunteer work in the summer. Zofie (Jaroslava Schallerová) is serious to the point of reticence and she is delighted with her friendship with Dominika. For the self-assured and superficial Dominika (Irena Svárová) the whole thing is just a momentary whim. When she leaves the work camp before everybody else, she doesn't even say goodbye to Zofie. The two girls meet again after the holidays as first-year students at medical school, and become close again during the nursing techniques class.
