Johan Falk: De 107 patrioterna (2012) on Netflix

Plot summary

The calm of Slottsskogen, Gothenburg's city park, is broken when two gangsters shoot at each other among the visitors. The police mount a wide operation, and the quarrel spreads fast through the Gothenburg underworld, pulling in several gangs. The GSI group takes the case and starts to trace a thread that looks bigger and more heavily armed than anything it has handled. A new gang is on its way into the Swedish scene, and Johan Falk is given the job of finding out who they are. Their single solid lead is a tattoo on the body of a gangster who died in the park.
