Apache chief Pierre Brice saves Assiniboine princess Karin Dor from a guy in a bear suit. He takes her back to her village and discovers that the Assiniboines have captured cavalry officer Terence Hill and two of his men. Brice has a plan to meet with colonel Renato Baldini and make peace, so he convinces Assiniboine chief Rikard Brzeska to let Hill go with a message for the colonel, who happens to be his father. Brice and all the chiefs will come to the fort and they'll all talk peace.
On the way home, Hill sees a brutal attack on a native village by a group of men lead by Klaus Kinski. He fights them off with the help of Lex Barker, who was conveniently passing by and also happens to be pals with Brice. Kinski is working for Anthony Steel, an oil baron who wants no peace because he can use conflict with the natives as an excuse to steal their land.
Baldini and the native chiefs reach a peace agreement, mostly because Hill agrees to marry Dor (who's in love with Brice, but both of them agree to take one for the team). Steel attacks a group of settlers and blames it on the natives. It's up to Barker, Brice, Hill and comedic sidekick Eddi Arent (who I didn't mention previously because he annoys me) to stop Kinski and Steel and save the day.
One of a series of West German westerns based on the books of Karl May that have Native American heroes even though they are all played by white Europeans. This is fairly typical Euro-genre fare, not all that coherent in the plot department, but a hell of a lot of fun. It's pretty much worth seeing just to see Barker, Hill and Kinski together, but it's also just chock full of great little action set pieces.
