After a chance encounter with criminals, an unusual gift suddenly manifests in him—temporarily rewinding back into the past. The ability, dubbed chronodiving, quickly becomes known to the special services, and Pakhom is offered a risky undercover assignment.
His task is to bring to light a major corruption network in Siberia, where, with the support of local officials, resources are being looted. Upon arriving on the scene, he is drawn into a story involving the brutal murder of a colleague-journalist and meets Anfisa, who is also conducting her own investigation. A partnership that began as cooperation gradually turns into something personal—and with each of their steps, the circle tightens, while the threat of death draws ever closer.
