Her husband Viktor and colleague Alexey do everything they can to support her, but a repeat examination shows that she is actually healthy: the test results were simply mixed up. Thanking her lucky stars, Svetlana decides to find out who is actually sick. But the results of her "investigation" shock her once again: the analysis belongs to her husband's mistress, with whom he has been secretly seeing for several years.
