The Crime ( Zbrodnia )

Floating offshore, a decaying corpse entangled in a fishing net is found by Agnieszka Lubczynska, a diabetic mother of 2 small children. Troubled detective Tomasz "Tomek" Nowinski is assigned to go to the coastal town of "Hel" to investigate. After the body is identified as Pyotr Miernus, his sister Ewa becomes a suspect but is soon found dead.

After having been drinking with Ewa, Josef Szarski flees the police but is apprehended and taken into custody. Unsure of guilt of Szarski, Tomek and his partner Monika now question the parentage of Pyotr and Ewa. Then the autopsy report sheds new light on the case.

While playing "Pirate" and then getting lost, Agnieszka's 2 children are found in a bunker by their frantic parents. The children's story of finding skeletal remains is reported by their mother to Tomek. The identity of the skeleton opens the case and leads to the conclusion.
