American Soldier (originally Der Amerikanische Soldat) was the third of Rainer Werner Fassbinder's "gangster trilogy." The film stars Karl Scheid as a German/American Vietnam veteran who takes a job as a hired assassin on behalf of the Munich crime lords. Scheid works both sides of the fence when three policemen engage him to knock off some awkward malcontents.
