An assassination attempt on the highest dignitary of the Catholic Church? According to providence, this is exactly what is supposed to happen on a certain day in September. When parts of the prophecy actually come true, the Vatican is seriously worried. The highest security measures are therefore in place for the Holy Father's upcoming visit to Cologne. Vatican security officers Andrea Conti and Paolo Naldini, as well as BKA officers Sara Stertz and Frank Dabrock, join forces to protect the Pope. At around the same time, former Foreign Legionnaire and precision marksman Rami Hamdan receives a mysterious assignment. For the horrendous sum of 25 million dollars, he is to take out a high-ranking figure. His destination is the cathedral city of Cologne.
