In ATR, nothing is what it seems. That’s why it is the Anomalous Territory of Radioactive Radiation, a layer between our world and the parallel one. A peaceful taiga clearing can turn into an anomaly that will tear you to pieces. A piece of hose on the ground will suddenly turn out to be a sticky predatory plant. A partner can suddenly hit you in the back, shielding the enemy from the bullet. And Artem Pavlov only at first glance ended up in ATRI by accident (he was called up to serve in the Separate Brigade of Military Rangers). And who really is is also another question...The first combat mission. All that is needed is to pick up people from a helicopter that made an emergency landing in the taiga, and escort them to the city through relatively quiet places. By the standards of ATRI, this is not a task, but an easy walk. That's why they send a squad of trainees. However, everything here is not what it seems. And a simple task can turn into a very difficult test, in which many forces will be involved, including a previously unknown clan of outcasts and creatures from a parallel world. And perhaps we will finally be able to solve one of the most mysterious mysteries of ATRI...
