The Movie is telling the true story about the
NSU Trio at original locations:

The so-called National Socialist Underground (NSU)
was a neo-Nazi terrorist organization in Germany
formed around 1999 to murder people with a migrant
background for racist and xenophobic motives. The
three main perpetrators Uwe Mundlos, Uwe Böhnhardt
and Beate Zschäpe came from Jena and lived in hiding
in Chemnitz and Zwickau from 1998. Between 2000
and 2007 they murdered nine migrants and a police-
woman, carried out 43 attempted murders, three bomb
attacks (Nuremberg 1999, Cologne 2001 and 2004) and
15 robberies. The number of those involved in the crimes
and their local, nationally networked supporters is
disputed. The environment is estimated at 100 to 200
people, including informants and officials of right-wing
extremist parties.
