At a mysterious party, six popular bloggers die. A team of young and talented people takes on the task of finding the causes of the tragedy. They don’t have investigative experience, but with their abilities they can look where ordinary people are barred from entering. A medium, a witch, an extrasensory psychic, a hacker, a runologist, and a barely noticeable girl who knows how to organize work clearly. They can handle this new case! But with every step, the investigation drives them deeper into a deadly trap, and the discoveries shatter everything that was familiar, as well as their faith in themselves and in each other. Someone believes the way out is to go forward, all the way to the end. Someone wants to retreat. And disagreements within the friendly team do not help with safety. The farther they go, the stronger the connection to the past becomes—personal secrets that each of them wanted to forget. The secret becomes clear, and the tragedy that happened in the present is directly related to events in the past. Welcome to the “Mysterio” Agency! Case one.
