BBC Four on 8 February at 9pm. Episode two follows at 9.45pm.
From the BBC's media centre:
Disguised as builders, a group of robbers descend on a top Belgium private bank - but the burglars have no eye for money or other valuables and target only 66 of 800 vaults in the bank. These 66 vaults belong to the country's industrial, financial, judicial and political elite, and the safe-deposit boxes contained their most intimate secrets - secrets that could bring down the nation.
Who ordered this hack? Who wants to disrupt the state? The bank scramble to cover up the robbery and avoid the involvement of the police, but police inspector Paul Gerardi (Filip Peeters) catches wind of the affair. With his incorruptible, old-school morals and devil-may-care attitude, Gerardi throws himself into the investigation, and when some of the key players are murdered, commit suicide or vanish, he soon realises just how big the case is.
Gerardi discovers that the victims are members of a secret organisation called Salamander. As he becomes the target of both the criminals and the authorities, Gerardi must quickly find out what their agenda is - and who is behind the thefts...
