At 25 years old, Yana Dvinskaya holds the position of director of the department of the Diamond Tear jewelry company. Her next goal is the post of vice president of the company. To get the desired position, Yana must convince the management of the northern diamond factory "Yarsky Put" to sell a stake. This can only be done in person, because the director of the plant, Varvara Bazarovna, is a person of the old school.
