The circumstances of the murder of Father Brenner, who was martyred and beatified five years ago, are still unclear. The 26-year-old chaplain was stabbed 32 times on the night of December 14-15, 1957, when he was lured out of his parish apartment under the pretext of urgent medical care. He became a martyr of the church persecution following the 1956 revolution, as he came under suspicion for his work with young people, which was viewed with disapproval by the state authorities of the time. The investigation depicted in the film provides insight into the restoration of Communist power during the post-1956 era.
