In the new explosion, random people were killed and public pressure puts more and more pressure on the research team - the case must be resolved quickly. At the same time, a young man is killed and Jakob stole the bomb. However, Jakob is raising money, the "bomber" doesn't care about his own well-being, but wants to leave something for his family. The attempt to blow up the ATM fails and DNA is found on the unexploded fertilizer bomb. The research team is on the verge of a breakthrough. Jakob compiles a list of enemies and parks a van full of explosives directly in front of the Riigikogu building.
