For Denis, talent in mathematics becomes fatal: the secret order of balance selects him as its number. For those for whom people are just numbers in an equation. Those on whose decisions other people's destinies depend. For those who have no right to make mistakes. Now his every step is determined by a harsh Code, deviation from the rules threatens death, and it is useless to wait for help. The only chance to escape is to use your wits and enlist the support of a team that has yet to be assembled. Denis begins a dangerous game. A game with a system of numbers and laws in which only a genius can survive.
