She seems to have left the movie world for actual rootin' and/or tootin' crime fighting in the Old West, lassooin' varmints and sidewinders who wear their jeans cuffed halfway up their shins.

I think she fell off her horse and hit her head, and this is all taking place while she's in a coma. I don't think she ever was a glamorous star, western or otherwise. She's living in one of those small seedy courts, surrounded by other peripheral Hollywood characters.
