Salamander (2012)

Brussels, Belgium. Sixty-six safes are robbed during a spectacular and bloody raid on the small but influential and extremely discreet private bank, Jonkhere. The owners of those safes form a select club of the most powerful people in Belgium, with high-level positions in industry, finance, the military, the law, politics and the unions. Strangely enough, while the perpetrators took no money, they did take documents. Pandora's Box has been opened. When a detective starts investigating, things become ugly.
