Piotr investigates the link between Daniel, his deceased brother, and Adrian Bogusz, a depressed businessman. Piotr begins a probe that puts his life -- and his family's lives -- on the line.

Piotr's associate Monika reports on a rumor about very prominent government officials; Piotr attempts to discover who “Abraham” really is and how he is tied to the deceased men and the very rich Tomasz Nawrot.

Along with his sister-in-law Ewa, Piotr looks for her missing son Kuba, and on their search they come upon a remote shack housing criminal evidence. Meanwhile, Piotr receives a last warning to abandon the case in the form of shocking violence.
