I'm trying to find this one movie that I watched a very long time ago. The plot was i think a army guy, one time in the past, he picked up a hitchhiker in sort of a sandstorm and the hitchhiker killed some of his army friends. Now he is kind of retired and he has a wife or girlfriend and he thinks they just picked up the same hitchhiker. He gets killed and his wife/girlfriend is on the run from the hitchhiker.
