Villafrid Gerster, heir to the Idavel gaming empire, entrusts a hacker under the nickname Orpheus with a task: to find the password for his father’s company accounts, which he hid inside a specially designed game “Midnight Knight” - so dangerous that the gamers previously hired by Villafried could not cope with the task. Orpheus connects to the game using a special capsule-mandrola, located inside the giant game server "Idavel", and finds himself in the gloomy world of "Midnight Knight" - only his name is no longer Orpheus, but Nemo, that is, "nobody". He needs not only to complete the task, but also to survive in a post-apocalyptic city full of mutants, high technology and strange magic.
