In a quiet provincial town, an unusual story unfolds, where big money collides with sincere human feelings. Wealthy and influential businesswoman Yulia Akhromeyeva decides to carry out an ambitious deal—to purchase an entire floor in the best building in town. However, her plans encounter an unexpected obstacle: four women live on the desired floor, each raising a child on her own. Akhromeyeva, accustomed to flawless deals, offers each of the residents tempting terms for an exchange. She is sure that one of these women will inevitably cause problems and ruin the entire chain of transactions. But fate has a far more unexpected surprise in store for her. As events unfold, it becomes clear that behind the outward appearance of single mothers are strong women with complicated lives. Their stories intertwine in the most astonishing way, and the deal that seemed like a simple business operation turns into a story of how a chance encounter can change a life.
