Twelve-year-old Iwo lives in a small, post-communist town that is home to the old and destroyed Black Mill – once a place of work for many parents. Breaking the promise to not approach the old mill, the children accidentally unleash its evil powers. From that moment, nothing will ever be the same again as people and things start to disappear.

A few years back tragic events tied the fate of three Catholic priests. From then on they meet on every anniversary of the disaster to celebrate their survival. On an everyday basis they have their ups and downs. Lisowski works at the curia in a big city, has a career and is dreaming of the Vatican. Problem is, archbishop Mordowicz, an opulent church official who uses his political influence to build the largest sanctuary in Poland, gets in his way. The second priest, Trybus, is a village parson. He ministers to a poor community and gives in to human weaknesses more and more often. Kukuła is not faring well either. Despite his fervent faith, he loses the trust of his parishioners actually overnight. Soon the stories of the three clergymen are going to join once again.

Giordano, an angel assigned to an orphan in Krakow, is two years into the job when his celestial overseers, citing budget cuts, initiate "Phase Two" without telling him. Some changes are good - they send him a nanny, the enterprising Irena; some are bad - his phone number to Heaven no longer works nor do his special powers; and some dismay him - he grows a penis. His closest friend tells him to get a woman, and Irena advises him on hygiene. He visits a therapist, Roma, and falls in love with her. She tells him its transference. Meanwhile, Giordano's celestial friends conspire to rid Roma of her boyfriend, clearing the way for Giordano to be his naive and engaging self.
