In the center of the plot is an exemplary husband and exemplary father Oleg. His life is measured and planned for years to come. But fate has its own plans: the young beauty daughter Alyona falls in love with the once best friend and peer of her father Anton, with whom they are united not just by friendship in the distant past, but by a stormy youth in all respects. So stormy that Oleg prefers to keep it a secret even from his family. As a loving father, Oleg is simply obliged to prevent the union of his only daughter with an immoral type, whose past makes him the worst candidate for son-in-law in the world. Anton continues to live that reckless life that both lived 30 years ago, but Alyona seems to like just such guys.
