A seemingly trivial case of a small carpentry business that has gone bankrupt under mysterious circumstances gets Mads' attention. Claudia is released after one and a half years in prison but her son is in Paris and the only work she can find is at a coffee shop.

Alf has rumbled Christensen's plan - a huge attack on the Danish krone. He and Mads try to stop it, but the attack is already underway and threatens to bring the whole country's economy to its knees.

Mads has to defend the police's handling of the hostage crisis in Nova Bank. He digs deeper and find that the bank forced the carpenter into bankruptcy.

Nicky and Bimse's friendship is tested when Bimse is questioned about the assault on a police officer. The fraud squad uncovers some unsavoury practices at Nova Bank, and Alf and Mads investigate a bank manager who is living well above his means.

Mads and Alf unravel the corrupt practices at Nova Bank, not realising that their boss Nanna is reporting their findings to Nova's chairman, the very man they are trying to bring down.

Mads and Alf, so far unable to pin any fraud on the chairman of Nova Bank, find a new lead and are able to bring him in for questioning. Nicky has an unexpected visit at the garage, straining his relationship with Bimse even further.

Nicky's assignment from Christiansen, to kidnap the granddaughter of his ex-colleague, proves troublesome and he desperately tries to cover his tracks.

After his failed assignment, Nicky has fallen out of favour with the Swede and is tipped over the edge when he can't get answers from him. At the Fraud Squad, Mads is more impatient than ever to get evidence against Christensen.

Claudia is feeding the police information about Christensen, but fails to give them any concrete evidence. Mads and Alf press her to lure him into a trap.

Mads waits nervously in the hospital not realising there is also trouble at home. His pregnant wife Kristina is woken by a noise in the dark as Nicky has broken into their home to retrieve the evidence against Christensen.
