Keko wants to bring his gang and the loot home safely. Dressed in burqas, the three bank robbers and three hostages board six taxis. To avoid further bloodshed, Schweinebacke orders no pursuit! When the gangsters gather at the meeting point, a surprise awaits them. Policewoman Billy also notices that someone is pulling the wool over everyone's eyes...

In the first season, a group of ambitious petty criminals led by mastermind Keko pulled off the coup of a lifetime with a spectacular bank robbery: diamonds worth several million euros. Their attempt to sell the loot to supposedly professional gangsters proves to be a fatal mistake in the second season, as the buyers turn out to be members of the ruthless Yakuza, the Japanese mafia. And they're looking to close a much bigger deal. When the deal falls apart in a karaoke bar, the gangsters become the target of a task force from an international police unit.

Stulle, Pepsi, and Barro want to sell the diamonds. Their friend Giovanni knows who can take the hot goods: Japanese men who run a bar near the Dutch border... Meanwhile, police officer Billy, with the help of taxi driver Otto, gives chase.
