In the Zone of Alien Anomalies strange things have begun to happen. Experienced stalkers started disappearing one after another, and each time before vanishing they were seen in the company of a mysterious stranger. Most remarkable: the abductor operated in the only pockets of safety in the Zone—bazaars, where everyone knows everyone well and where video surveillance is in place. However, to everyone’s surprise, each time no one saw or noticed anything, and the outside surveillance cameras all failed at once. Pokatilov— a businessman with great influence in the Zone—flares up with anger because his best workers, thanks to whom his business thrives, are disappearing. To unravel this mystical case, the local bigwig sends his favorite—stalker Kex— as a partner for him, but his companion turns out to be a mysterious and very strange drifter nicknamed Psykh. However, solving the secret isn’t that simple, and the companion has far more secrets than the unknown abductor.
