[1] In the series criminal cases are shown in which the Church and the police have to work together, given a pastor of the Catholic Church in Germany is not allowed to investigate alone.
Monsignor Simon Castell is a Jesuit who is specially commissioned by the Vatican to solve criminal cases all over the world, always in connection with the Church.
[2] Father Castell therefore has to acquire a wide variety of skills, such as flying aeroplanes, opening locked locks and doors, learning self-defence and even repairing motorbikes.
[3] To accompany the 1st season, ZDF broadcast 4 so-called webisodes in the channel's own media library, short stories in which the Father's back story is told and how he was trained as a special agent.
[4] The series has been described as very popular[5][6][7][8] and called "James Bond in cassock" by the Frankfurter Allgemeine.
