Sam trouwde met Barbara voor haar vaders geld, maar de oude man wilde maar niet dood gaan. Maar nu is het eindelijk zo ver, zijn schoonvader is dood en nu kan hij zijn vrouw op gruwelijke wijze vermoorden uit wraak voor de jaren dat hij haar heeft moeten dulden. Hij moet zijn plan echter wijzigen als zij ontvoerd blijkt te zijn.
