One Sunday after the mass, in an overly Christian village, Petar, a priest devoted to his profession, wants just one thing: enjoy an ice cream.

This film follows father Ahmed and son Tarik Karaga during WWII and the Siege of Sarajevo.

The main focus of the story is a young girl, Maša Artuković, allegedly possessed by Satan, whose deteriorating state results in the arrival of Viktor Supilo, a priest who is to conduct the rite of exorcism upon her. The ritual is to be performed in the presence of Maša's sister Vera, a known psychiatrist Sofija and an unannounced crew of TV reporters that want to expose exorcism as a controversial and dangerous ritual that has no place in the modern Catholic Church.
