Dieci bianchi uccisi da un piccolo indiano (1974) Blood River

Dark romantic western, Rosalba is in love with Ringo ( FabioTesti ) but marries Ben Webster for money and security.  RN will also sleep with Ringo whenever he wants, but when she becomes pregnant, the situation soon spirals out of control.  Her husband finds out and almost kills Ringo, but RN intervenes by stabbing her husband in the back ( literally ). A very pregnant, distraught & rain soaked Rosalba then gets to watch her man go down in a hail of (bloodless ) bullet hits @ the end.
