Brian Kessler, a journalist researching serial killers, and his
photographer girlfriend Carrie set out on a cross-country tour of the
sites of the killings. Sharing the ride and their expenses are Early
Grayce, a paroled white trash criminal, and his girlfriend Adele. As the
trip progresses, Early begins to appear more and more unstable, and
Brian and Carrie begin to fear that they may have a real-life killer in
the back seat of their car.
