A couple driving down a lonely road have a bag of money thrown into the back seat of their car. The temptation to keep the money leads them into blackmail and murder. The basic premise has been used several times, but this version has some good plot twists and there is a good performance from Lizabeth Scott as the woman maniputaing men for her own ends and money.
