Anomalous stalker Pyotr Panov, nicknamed Peter Pan, continues the search for his kidnapped children. The path is long and difficult: former friends unexpectedly turn out to be enemies, and the native office begins the hunt for a former employee. In addition, foreign intelligence has become interested in the developments of Vivarium and is not averse to getting to Panov, who knows many of the secrets of zonal science... Constantly entering into battles and escaping from pursuit, he does not forget his main task: to save his twin daughters. The trail again leads to the Zone - and Peter Pan goes there alone and without a weapon, with his pursuers hanging on his tail... There he finds new allies, who can be called people with a very big stretch, and new enemies are added to the old familiar dangers and traps of the Zone. Will you be able to walk along the blade of the knife and achieve your cherished goal? The chances are slim, but Peter Pan is not used to retreating and giving up.
