IMDb says, "Indians attack a stagecoach, and a disparate band of passengers must band together to fight them off. "
It forgets to mention an hour of pre-indian attack of building up to the confrontation with the EVIL UNREASONABLE INJENS! Meanwhile we meet such characters as the sexy naughty actress, unflinching bad ass criminal cowboy, horny pacifist senator, identity theft victim and the honest dad. Guess who gets killed first.
This film must have snuck in among all the rest of the Westerns that Hollywood was jerking out as often as possible in the 50's. It is just a great example of something that got churned out using all the cliches in the book.
It's available on netflix...which is how I found it.
