Now I've learned that it came out in 2008. Since it didn't get one word of publicity, perhaps it went straight to DVD.
Here's the summary on IMDB.com:
This still could be a great movie, although great movies usually don't disappear without a trace. Or it could be what I called it before: "a romanticized look at Southwest Indian life with none of the harsh realities." Only time will tell.
