In the aftermath of the fall of the Iron Curtain a clandestine far-right German terrorist group called National Socialist Underground or NSU began operating in Germany by killing immigrants in cold blood, termed the Bosphorus Serial Murders. The victims are brutally slayed with the same gun. The police never even consider a right-wing conspiracy â€“ despite evidence to the contrary â€“ and focus on internal ethnic feuds. So while these decent people are dying, the German authorities are heaping scorn on them, accusing them of drug dealing and hinting at loose morals. Hovering above them are three comrades who've been arrested and let go time and time again: Beate, BÃ¶hni and Uwe.
After German reunification, the neo-Nazi National Socialist Underground begins a killing spree while cops fight an uphill battle to catch them.
