The Czech police have turned their suspicions towards the journalist Grimmer and the young detective Suk for the murders of their former police chief and three former Czechoslovakian secret police members. Even though he is a suspect, Suk meets with Grimmer to find out the truth.

Nina doesn't know that Johan has disguised himself as her and is confused when people in the street affectionately call her "Anna." Meanwhile, Tenma and Grimmer meet with Captain Karel Lanke, a leader of the former Czechoslovakian secret police.
