Betty,
First of all, WELCOME to the Original John Wayne Message Board! You have joined with a friendly, knowledgeable group of fans that come from all around the world!
In answer to your question, the movie is Tall in the Saddle, one of our (personal) favorite John Wayne movies! The woman has been a thorn in Duke's character's side throughout the whole movie, and she is unaware of the whole situation, just knows what (she thinks) she sees.
I highly recommend the movie!
Again, welcome!
Chester 
and the Mrs.
