In a blackmail video posted online, the Norwegian Cyber Defence is challenged. The hacker "RAMRUN" demands that a staggering amount of money is transferred to a particular bank account.

Whilst the country holds its breath, the Cyber Defense seems powerless to act. The threatened blackmail is carried out, and more threats are issued. Lars dedicates himself to try and uncover Ramrun’s identity.

Everything takes a completely different turn when the hacker’s threat appears to have come from Lars’ own computer...

He now has to start the fight to clear his name. Nora and Simen assist him, and in addition he gets help from the German hacker Mitnick.
