These types of films seemed to be quite common in the 1950s. Drivers making the foolish mistake of picking up the worst possible type of hitch-hiker--a criminal. One who might take him hostage or kill him at any moment. A very real fear of the possible.
This film feels like a mix of THE HITCH-HIKER and THE DESPERATE HOURS but isn't quite on par with either. Unlike those, this feels like a Made For TV film. The Narration is very much a negative and will probably make many laugh due to its dire seriousness.
But the characters in this film are well-played and certainly entertaining enough to make this film an enjoyable ride. Especially good are Hildy Parks as the terrorized wife who won't stand for it and Jack Kelly as her husband who is thinking only of his family's welfare. John Cassavetes is also good in his role as the mastermind criminal. There's some terrific cinematography in the film featuring scenes out in the desert and the climatic ending in the rain.
