Sezon 2

Hallgrim moves into the Opera Hotel to recuperate and, like the hero in the Hitchcock film Rear Window, becomes fascinated by a beautiful young woman in a flat opposite. When he sees a man enter and start beating her, he films the attack and he recognises the man as Benjamin Stern, an unscrupulous member of the Israeli mafia. He later discovers a disturbing connection with a child pornography ring.

Through blackmail, Benjamin Stern secures a matrix of a Euro. All he needs now is the special banknote paper that is being transported through Berlin in a camouflaged garbage truck. Hallgrim learns of his plan. In an effort to sidetrack the police, Benjamin gets a drug addict to drive a van into a schoolyard in Berlin. There's a bomb in the back, which is set to go off at noon.

Hallgrim continues his hunt for Benjamin Stern who is deeply involved in the blood diamond trade from Congo. Michael finds an e-mail on Benjamin's computer to Le Mabë who is wanted in connection to war crimes. The mail also refers to two Congolese women who have sought asylum in Denmark, both of whom have been subjected to cruel rapes. Meanwhile, Hallgrim starts up a romance with a Swedish Flight Attendant.

A Danish businessman who has been trading weapons for tantalum with Le Mabé, is blackmailed by him. Meanwhile Le Mabé is hiding in Denmark with his former child soldier from Congo.

After Fabio kills Le Mabé with an injection of nerve gas, Hallgrim learns about some incriminating photos. Michael finds an internal leak and Hallgrim decides to lay a false trail. And, Marie finds out that Hallgrim slept with the Swedish flight attendant.

Curly, the mole in the squad, leads the team to ponder what Aagaard's latest development in Congo, a field hospital, really is? Could it be a cover-up for a facility to install a rebel leader, who would grant him mining concessions to the element tantalum.

Hallgrim's team is sidetracked in their search for a suspected suicide bomber who may be planning an attack at the wedding of an Iraqi professor's daughter, in Copenhagen.

Hallgrim and his team try to stop a known terrorist called "The White Prince of Denmark" and Amina, a convicted criminal, from detonating a bomb on a school bus.
