The Hitch-Hiker (1953)
The Hitch-Hiker (1953) Ray (Edmond O'Brien) and Gilbert's (Frank Lovejoy) fishing trip takes a terrifying turn when the hitchhiker (William Talman) they pick up turns out to be an armed sociopath on the run from the law. He's killed before, and he lets the two know that as soon as they're no longer useful, he'll kill them as well.
