Katya is damn smart. And Dima is not only attractive. He has money and his own serious business. The only thing left to do is to take him away from his wife and live in luxury. You just need to try a little to “turn on” the feminine charms. The unhappy businessman rushes between his women, gives cars and promises - as if walking on a sharp knife. And it is not clear who ultimately stabbed him with this very knife. What was it? Revenge for hurt feelings? Or attempted murder for money? Major Tabachny and Opera Ploshnikov were knocked off their feet, unraveling a tangle of passions, until they finally came across the third suspect - Rita, an old friend of Dima's wife and part-time... his mistress.
