Five girls are in mortal danger. At least, this is what the elderly Varvara Stepanovna says, who called Nadezhda Lebedeva on the phone. True, the old woman persistently calls Nadezhda Tasya, and her story very much looks like senile nonsense. But Nadezhda still decides to check the information. Oh, it wouldn’t be worth it... First, what she finds out is that Varvara Stepanovna has been killed! Secondly, one of the girls discussed in the telephone conversation is dead. And these are just the beginnings. The flowers begin when a gangster-looking man appears in Nadezhda’s apartment, calling himself Tasya!
