Four years after leaving Bieszczady, Prosecutor Iga Dobosz is drawn back to the turbulent border region to confront a chilling new crime. The area is simmering with tension – increased illegal crossings are pushing Border Guards to their limits. Captain Markowski has solidified his leadership, but old ghosts refuse to stay buried. Meanwhile, fugitive Rebrow remains hidden deep within the unforgiving Bieszczady wilderness, clinging to survival and maintaining contact with just two confidantes: Łuczak and Marta. His carefully constructed isolation is shattered when an unexpected arrival – an illegal immigrant – disrupts his refuge.
