A whirlwind of crazy events bursts into the sleepy kingdom of the lonely old maid Eva Drozdova, vegetating in a paper routine. First, a foreign car with a bald businessman at the wheel, whom kind Eva immediately drags into her precious Zhiguli... to a nearby morgue for medical assistance. Then suddenly his handsome stepbrother shows up and sponsors Eva’s trip to sunny Bulgaria. But there is no happiness - there are only corpses, corpses, corpses all around... Even the best friend turns out to be a terrible poisoner. It can't be that all these murders happened just like that! - thinks Eva. And indeed. It soon becomes clear to her: the criminals pretending to be friends are looking for something valuable. And they will find it - if Eva does not retrain from an old maid into a swashbuckling detective!..
