The story of a writer who accidentally stumbles across the elixir of immortality and in doing so encounters the small group of immortals who have jealously guarded this secret for centuries. Once the writer has knowledge of this elixir, called 'Mafussalin', the group of five immortals give him a stark choice: either join them, with the price of admission, being a duel to the death between the immortal who accidentally gave the secret away or death at the hands of the group. As the writer makes up his mind, sometimes aided and at other times opposed by the ever shifting alliances from within the group, we discover how the other immortals became this way, their true ages and what they have done with this 'gift'.

In a small Russian town, there is a Research Institute for magic. One of the witches, Alyona Sanina, is going to marry a guy named Ivan Puhov (not a magician).

Alyona's friends call Puhov to the rescue.
