Vile

This movie is about a group of 20 somethings who after a trip away are on the way back home when they stop for gas. While at the petrol station they meet a woman who needs a ride to her car after running out of fuel. They drop her at the car when all of a sudden they are knocked out. They wake up in a strange house to find another group of people there, and they also discover that there is something attached to their necks. Then they all find out that they have to endure torturous pain to fill up the device which will eventually let them out of the house. But it obviously won't be as easy as they think.
