Mikhail, Sergei Popov, a truck driver, arrives at a factory construction site and helps pull a car out of the mud. There he meets Lyuba Nina Ruslanova and her friend Nikolai Aleksei Zharkov, and soon he gives them a ride to a lively Komsomol wedding ceremony where several couples celebrate together. Lyuba delivers a warm congratulatory speech, and this small moment signals the start of a connection that will grow over time. As their bond deepens, Mikhail’s presence stirs jealousy in Nikolai, who believes Lyuba should belong to him.
Back at the construction site, Lyuba’s colleagues—a group of plasterers who work alongside her—offer practical advice, urging her to consider marriage with either Mikhail or Nikolai. In the evenings, Mikhail often picks Lyuba up after work, and their conversations ride along in the truck as Lyuba heads to a shared trailer where she and her friends live. Each drop-off blends everyday routine with a hint of growing affection, while Nikolai’s uneasy greeting greets them when Mikhail arrives first. The tension between affection and ownership lingers beneath their words, adding a quiet chord of complication to their days.
One night, a simple act takes a turn: Mikhail helps a stranger fix her car engine on the roadside, and Lyuba discovers a love letter discarded by the stranger, a small, intimate detail that lingers in her thoughts and nudges the story toward a choice that feels inevitable.
The factory is finally completed, and a celebratory mood sweeps through the workers as they prepare to move into a newly allocated apartment building. Dressed in a suit, carrying flowers, Mikhail arrives near the building where Lyuba waits with her belongings, and he proposes. The moment is softened by the hope of a fresh start, yet the scene also foreshadows the obstacles they must navigate. He suggests they quickly register at the registry office, acknowledging the long line ahead. In the shadows of the moment, Nikolai steps away, defeated, and leaves behind a broken mirror clutched in his hand, a stark image of his heartbreak as he watches Mikhail and Lyuba share a quiet, tender glance they had admired themselves in.
Together, the story traces a path from chance encounter to a hopeful proposal, set against the steady, working rhythms of the construction site and the intimate, unresolved tensions among three people who are drawn to one another, all while the world they inhabit hums with the ordinary, human rhythms of labor, friendship, and love.
