Als Indianer verkleidete Gesetzlose begehen Verbrechen gegen Siedler, doch Winnetou und Old Surehand sind entschlossen, die Banditen zu entlarven und den Frieden zwischen Siedlern und Indianern zu wahren.
"Unter Geiern" or "Frontier Hellcat" or "Amongst Vultures" is a German-language movie from over 50 years ago and one of many installments to the pretty successful Karl May western series. German audiences really loved it back then.
I've seen more than several of these Karl May novels adapted for the screen and I'm not yet sure who has the better imagination. Its quite obvious that these are totally unrealistic depictions of ruthless heathens and downright savages trying to be put in a kinder light for whatever purpose that has yet to be explained.
Continuing in the tradition of previous German-made westerns based on the books of Karl May, this later entry can't hold a candle to earlier films such as "The Treasure of Silver Lake". This one has Granger as leading man and, though he has occasional moments of wit and presence, for the most part he isn't interesting enough to carry the film.
