Young bricklayers Franta Doubrav and his friend Béla meet two girls, Mařka and Vlasta, on their way back from a friend's wedding, but they only manage to call them by their name and the construction site they are currently working on. Imagine their surprise when they discover that Mařka is a trained bricklayer who has joined Franta's father's work crew, where she proposes a new way of working that will help catch up on the construction delays. As a young girl, however, she must first deal with the distrust of the older and more experienced bricklayers.
