Young German surveyor comes to the Wild West to survey for the railroad being built; Apache tribe protests against uninvited railroad on their land; Apache chief has this marvellously beautiful and impressive son about the age of said young German surveyor who is marvellously unimpressed and disdainful about all these white people; railroad people and enemy Indian tribe take Apache delegation incl. that son hostage; young German surveyor sekritly sets them free; fighting ensues when the Apaches come back; surveyor is injured and taken captive, then at the abandoned pueblo where the Apache tribe lives nursed back to health by the daughter of the chief/siser of the beautiful son; surveyor must do trial by combat against the chief's son to save his own life and that of all his comrades that were captured as well; in great bare-chested wrestling, he wins, only then produces the proof it was him who freed the Apaches, in shape of a lock of hair that he'd cut from the chief's son's oh so lovely long black hair; they swear to be BFF before all the tribe; at night, they meet by the river to talk about how much they really care about each other; the chief's son teaches the surveyor everything he needs to know about surviving in the wild, which involves much sneaking about in the shrubbery; when the chief and his daughter get murdered by the baddies, the son becomes the chief of the tribe, and together, the (now) chief and the (former) surveyor fight crime have these many many adventures in the Wild Wild West...

Actually, somebody who cares about the whole thing more than I do should re-write the whole thing as outright slashy fic.
