In 1484, Pope Innocent VIII promulgated the bull “With all the strength of the soul,” which officially declared witchcraft a heresy and marked the beginning of a great witch hunt. Shortly before this, the union of inquisitors created their own secret order - the Trinity. The trio is engaged in the abduction and elimination of unwanted persons. Illegal interrogations and torture become a means for the order to gain power and wealth. Diamond is a witch hunter working for the Trinity: strong, fast, able to act stealthily and carry out assigned missions with precision. He does not believe in higher evil and works only for hard cash. But the kidnapping of another victim of the order sets off a chain of events, after which many innocent people suffer. Gradually, Diamond begins to doubt that he has chosen the right craft. His battle against the Order of the Inquisition begins. A battle in which he will have the opportunity to know himself and try to correct his mistakes.
