Doublecross(2000)

In the remake of DOUBLECROSS, Tina Krause stars as a spoiled little rich girl whose father refuses to give her any more money. She decides to make it appear she’s been kidnapped so that her rich father will pay the ransom and she’ll get the money she wants. But her stepmother (Debbie D) learns of her plot and sees a way to get even for her stepdaughter’s previous behavior. Debbie forces Tina to strip, ties her up, and puts a dog collar around her neck to keep her in line. Then when Tina tries to escape, Debbie forces her to put the dog’s favorite ball in her mouth and then it’s taped in place. But Debbie’s accomplice has his own plans and leaves both women tied back to back, completely naked, with the gas turned on!
