While driving down a dark, isolated road, Abbey grips the steering wheel when the car behind her bumps her van-camper with the intent of pushing her down the mountainside. The bumps continue, but she manages to keep control of the van. The assailant turns off the road at the edge of a town and disappears before the police arrive. The illusion of escaping from the assailant was broken the next morning, however, when she visits the campground office and discovers an unknown man had asked about her. He knew her name and described both her and her RV.
She has no idea who this mystery man might be or why he wants to hurt her. Paranoia sets in, but she continues traveling northward hoping to elude her pursuer. Her dream vacation had turned into a nightmare.
