Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This is a low-budget western with some great New Mexico scenery, a bunch of inexperienced actors who look right for their parts, and made by a good director. I thought that the three women protagonists would make it worth watching since there are few westerns with good roles for women, but it doesn't really work. The best thing I can say is that the movie passes the Bechdel Test for the active presence of women in movies. That means the movie is not entirely sexist, but it doesn't mean it's any good.
After watching their husbands hung in the middle of town, the three women return home, shoot it out with the townsmen, then get on their horses and ride away. That starts the chase part of the movie which is mostly the chase. Besides the posse following the women, there's also a corrupt preacher and his gang of Mexicans, a couple of Pinkerton detectives, a band of Apaches, and a fourth Thornton brother nobody knew was alive, all chasing after them to find out where the money is hidden. They get shot at and tortured along the way. And, in a really crazy twist, the women keep seeing and talking to the ghosts of their dead husbands. They encounter a young boy on their journey holding a dead lizard on a stick. He asks them if they want some. They decline. He apologizes, saying he couldn't find a rattlesnake to eat.
