Scream for Vengeance!

EVERYONE HAS A BOILING POINT... THEN COMES THE... SCREAM FOR VENGEANCE! Four robbers break into the home of wealthy jeweller Anthony Lomas. Returning home with his wife and daughter, Lomas is surprised and one of the robbers, Luke, takes the women as hostages. Lomas is brutally murdered by the other three crooks when he accidentally triggers the burglar alarm while opening his safe. Luke, meanwhile kills both mother and daughter after raping the girl. As the robbers flee the jewellery store, they take as hostages Jenny Bradley, grand-daughter of a United States senator, and her boy friend Mark Davis. Back at their hideout, they learn the identity of Jenny's grandfather and decide to hold her for ransom. Three of the crooks depart with Jenny's recorded plea for help, leaving Mason to guard Mark and the girl. Mason is knocked unconscious by Mark after the robber has molested Jenny. The young couple find a store of guns in the house and kill Mason when he comes after them. Trying to escape in a truck, they encounter the returning members of the gang and a wild chase follows across the fields. Hiding in the undergrowth, they shoot one of their pursuers dead. The survivors, Dreyer and Gandon, re-group and Gandon shoots Jenny in the leg. Mark engages in a vicious hand-to-hand battle with Dreyer while Jenny, finding a fallen gun, brutally shoots the robber. Still on the run, Mark and Jenny find shelter in an old barn. Mark goes for help, leaving Jenny behind with a pistol. Gandon, now the only surviving member of the gang, manages to shoot Mark, then tries to rape Jenny when her gun is empty. As she struggles, a critically wounded Mark staggers in and fatally impales Gandon with a pitchfork in answer to Jenny's agonised "SCREAM FOR VENGEANCE"...
