Wolf Creek (2005) on Netflix

In 1999, Ben Mitchell and his two British girlfriends Liz Hunter and Kristy Earl buy an old car to travel through the outback of Australia with little money. Their first stop is to visit a meteor crater in the isolated Wolf Creek National Park. When they go to their car, they find that it does not start and without option, they decide to spend the night in the car. Later, a local friendly man, the hillbilly Mick Taylor, stops his truck, offers to help the trio, finds that they need to replace the coil and proposes to tow them to his camp, where he could fix the car. When they accept the proposal, their dreamy vacation turns into a scary nightmare.
