Copenhagen 1949. When young, idealistic journalist Bjarne Madsen receives a tip-off about organised crime and black marketeering on a grand scale he decides to unravel the threads of the extensive network and work his way to the “Spider” himself. A highly esteemed crime reporter tries to dissuade him, but Bjarne is fearless—even when it transpires that there may be links from the Copenhagen underworld leading to the top echelons of the police force.
