Terror at Tenkiller
Terror at Tenkiller is a 1986 horror film directed and produced by Ken Meyer, and written by Claudia Meyer. The film was shot entirely in Oklahoma near Lake Fort Gibson and the Fort Gibson dam, though not at the actualTenkiller Ferry Lake as the story suggests.
The next day, a pair of coeds, Leslie and Janna, head to Jannas summer home near Lake Tenkiller for summer break, and to get away from Leslies abusive fianc, Josh. At the lake, the two get summer jobs at the diner Denise worked at during previous summers, and meet Tor, who takes an instant liking to Leslie. Shortly after Leslie and Jannas arrival, Tor stabs another waitress, Debbie, to death in a hot tub, and knifes and dismembers his lecherous boss, Preacher, outside of Jannas place, after catching him spying on the women. After awhile both Leslie and Janna grow to trust and like Tor and offer him to come to their cabin for a beer which Tor agrees to do soon enough. By this time the two women receive threatening voicemails left on their cabins phone and assume its Josh. They pay little mind to it and continue life as usual. Later on Janna goes out to tan on the dock while Leslie is working the closing shift alone at the diner. Tor visits Janna and Leslies cabin for a beer and murders Janna by stabbing her in the back as shes washing her hair. Meanwhile, Josh is looking at maps, making phone calls, and chain smoking presumably trying to locate Leslie.When Leslie returns home from work she finds Jannas body and believes that it was Josh who killed her. Tor consoles Leslie and soon plays a harmonica and admits that he was the one who killed Janna because he believed that she was a corrupting influence on Leslie. Tor then begins to tell her how much he loves her. Leslie runs off into the wilderness after slashing him across the face with a car key while he professes his love for her. While chasing Leslie, Tor hears Joshs car pull up, and murders him by slashing his throat, leaving his corpse propped up in a room for Leslie to find when she returns to the house. Knocking Leslie out when she finds Joshs body, Tor places her in his boat and starts rowing across the lake, but is knocked overboard and seemingly drowns when Leslie awakens and swims to shore.
