KMC Forums - What's the name of this movie?

I watched movie, in progress; had to leave before the end.
Can you tell me the name, from this summary?
Two english-speaking white females on horse back, in arab desert, with a guide. One woman is separated from the party, by a sandstorm(?). She is found by an english-speaking arab, who turns her over to group of arab traders, instructing them to "return her to the station" which she had described.
The head arab trader takes her "home", pitches a tent for her, and treats her as a wife, to the dismay of his 3 arab wives and their children.
When the trader leaves to return to his rounds, the arab wives take the white wife to market place and lose her ...

I saw it on one of the Cable movie channels about 1999/2000. Don't know the name of movie, or any actors. Can anyone help me, please?

Much appreciated.
Thank you.
