Prying into someone else's business, getting involved in criminal disputes - this is the favorite pastime of the restless Zhenya! She does not deviate from her rules even on vacation in Crimea. True, the caring husband assigned her cousin Dusya to Zhenka, so that the cultural holiday would not turn into one continuous investigation. But this didn’t help either! Quite unexpectedly, Zhenya witnesses a conversation between two boys who are going to rob a rich St. Petersburg jeweler. So the adventure begins! But Zhenya promised her husband not to get involved in criminal adventures. But she won’t - because with the help of her sister she will try to prevent a crime. Whether this will work out or not remains to be seen. But the fact that Zhenya is already under surveillance is visible to the naked eye.
