A botched burglary leads to the arrest of the Jönsson gang’s leader, Sickan. After serving ten months in prison, he is released and unexpectedly recruited by the enigmatic banker Wall-Enberg Jr. to steal the legendary Bedford Diamonds in Switzerland. Though Sickan successfully carries out the heist, he is betrayed and nearly captured. Returning to Sweden and reuniting with his old accomplices, he sets out to take calculated revenge on the man who double-crossed him.
