De schat der blauwe bergen

Winnetou and Old Shatterhand arrange a conference, in which the Chiefs of different Indian tribes meet with white politicians and generals to negotiate a final peace treaty. The reckless businessman Forrester (Anthony Steel) and his vicious private mercenaries - who don't back up from any kind of crime, including child murder - are thoroughly against these diplomatic efforts. Forrester objects to these "soothing politics", intending to exploit the rich oil fields centred on the Ponca tribes land. And, just as Winnetou is prepared to sacrifice his love Ribanna (Karin Dor) to a "white" Lieutenant (young Terence Hill, here still as Mario Girotti) to benefit peace talks, Forrester´s mercenaries attack a peaceful group of settlers and put the blame on the unsuspecting, innocent Indians. Old Shatterhand, more or less coincidentally the only witness of the attack, has to fight the seemingly unavoidable escalation between the Indians and the white settlers, with the help of his blood brother, Winnetou.
