A fishing trip turns into a journey through hell when two men pick up a homicidal maniac by the side of the road. The hitch-hiker has left a bloody trail of death across the countryside. His latest victims are forced to drive him through the desolate wilds of Mexico as he tries to make a getaway. Knowing that they may be killed at any time, the two men desperately struggle to escape. Their captor psychologically tortures them, destroying any hope of survival. As their sanity unravels, the prisoners confront the madman in a final violent showdown. The Hitch-Hiker is a film-noir thriller and is one of director Ida Lupino's finest moments.
