A group of former classmates rent a country house for a relaxing holiday, just like in the good old days. The modern chalet has everything for a comfortable and fun vacation, including a smart speaker called "Alena." "Alena" knows how to entertain her guests and has many "skills." She can solve puzzles, manage the house, and even knows all the "skeletons in the closet" that her friends are hiding. The device invites the group to play a game of "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.
