Police Major Danilov is a scumbag and a coward. But as usual, he is in good standing with his superiors. However, an unexpected act during a major raid puts an end to his future. Now he has only one chance to maintain his freedom - to agree to participate in a mysterious experiment. The choice is small, but something goes wrong: during the experiment, Danilov suddenly loses consciousness and wakes up in his own past. It’s October 1995, he’s thirteen years old again, and there’s exactly a week ahead before his younger brother disappears without a trace and his mother commits suicide. The chance to prevent something that once changed your life forever is a great gift, but fighting the past turns out to be not so easy. Long-forgotten details take on a new sinister meaning, and the rising events of the past are monstrously rearranged, bringing the repetition of the catastrophe closer. There is only one fragile hope left: to try at the age of 13 to become what he never managed to become in adulthood - a real policeman.
