Four years have passed. The borderland remains unstable; more and more people are crossing the border illegally, and the Border Guard operates under enormous pressure. Prosecutor Iga Dobosz (Aleksandra Popławska) returns to the Bieszczady to lead an investigation into a gruesome crime. Markowski (Andrzej Zieliński), who keeps the unit under firm control, has earned the trust of his subordinates, but the events of the past continue to haunt him. Grzywa is dead. Rebrow (Leszek Lichota), pursued by the justice system, is hiding deep in the Bieszczady wilderness. He struggles against the harsh natural environment and remains in contact only with two friends — Łuczak (Jacek Lenartowicz) and Marta (Anita Jancia-Prokopowicz). Everything changes when an undocumented immigrant, Alsu (Anna Donchenko), appears at his hideout.
