A group of former classmates rent a country house to relax like in the good old days. The modern chalet has everything for a comfortable and fun vacation, including the smart speaker "Alyona". "Alyona" knows how to entertain her guests, she has many "skills". She can solve puzzles, manage the house, and she also knows all the "skeletons in the closet" that friends are hiding. The device invites the company to play the game "Find the Killer" and find out the circumstances of the death of their best friend, who died less than a year ago under strange circumstances.

Nadya is a successful otolaryngologist-surgeon, but by the age of 40 she suddenly realized that she didn't know anything about herself at all. Every day at work, she examines the sensory organs of patients, but she has forgotten how to hear her own feelings, or maybe she has never heard them. Her husband Boris left her two years ago, unable to stand the routine, although the couple is still not divorced. Nadya brings up her daughter Oliviya and continues to live in her mother-in-law's apartment. Nadya needs changes to see that there really is a lot of love in the world. And in her life there are six "lessons of tenderness", each of which will help her to find herself again, her own voice and her new hope.
