Laura,
Welcome to the John Wayne Message Board, the best of its kind this side of dot com! 
Our experts have been looking into your request and haven't come up with a final solution yet.
Just to muddy the waters a little more, is there a possibility it might be a Roy Rogers film? I seem to remember a story line like the one you describe.
Anyway, if it is a John Wayne movie, you've come to the right place to find an answer!
