Helldorado

Arthur T. Ryan, a hitchhiker, gets a ride from haughty, society girl Glenda Wynant and her fiance, wealthy J. F. Van Avery after he helps them to replace the top of their convertible when it begins to rain. As they approach a bridge, Art notices a few stalled cars, and when the storm worsens, the bridge washes away, leaving Art, Glenda, Van and several others stranded in a canyon.
