Gunsmoke - Season 7 Episode 6

Sarah Drew arrives in Dodge City hoping to find someone to escort her to Ft. Wallace so she can marry her fiancée. But everyone she talks to tells her the distance is much too far and the prairie is much too dangerous and inhospitable, especially with Indians on the warpath. She's told she'll have to wait until the situation improves. When she learns that Matt needs to cross the prairie on business she follows him in a buckboard. Matt can lose no time returning her to Dodge and reluctantly agrees to let her come along. During the journey they are set upon by a raging prairie fire and lose their horses and supplies. Then, Matt gets hit with an arrow during an Indian attack. As if that isn't enough, when Sarah goes for help the man she brings back turns on her with the intention of molesting her and killing Matt!
