After a botched assignment, Mick is demoted and sent out onto the streets as a patrol officer. But Andreas is also having problems in his new job at the State Criminal Police Office. His colleagues don't accept him, and his boss Koller believes Andreas is trying to blackmail him.

After the attempt on his life, Andreas wants to quit his job. But Mick convinces him that he can only protect himself and his family if they solve Koller's death. During his unofficial investigation, Mick comes across a blackmail email.

Mick finds no answers at Klaus Koller's funeral. However, he notices that he is being watched. When he tries to confront the person, the man escapes in a car. But he has seen the car before – in front of his daughter Isa's house!

Mick gains access to a restricted LKA file containing a list of people who were involved in the big heist on New Year's Eve 2001/2002. There is a blacked-out name with seven letters on the list!

Everything points to Mick having been involved in a serious crime. Apparently, he was not in a coma on New Year's Eve 2001/2002, but was involved in a strange incident involving a transport of millions of Deutschmarks.

Now that Mick is suspected of murdering Bundesbank official Höthker, he flees to Monaco. There he wants to track down his father Erwin and question him about the events of New Year's Eve 2001/2002.

Mick is finally about to find out what really happened on that fateful New Year's Eve and to what extent he was involved in the crime. Meanwhile, the air is getting thin for Andreas, because his partner Anja is also involved in the matter.

Mick finally finds out who is responsible for the blackmail and murders. Ultimately, he must face his toughest test yet: his adversary has kidnapped Astrid, who is pregnant, and threatens to kill her if Mick doesn't let him go.
