Adam (Eric Jungmann) and Harley (Justin Urich) drive a red 1970 Chevrolet Kingswood across the country so Adam can tell his ex-girlfriend he still loves her before she gets married. After an encounter with a hearse, the two stop at a pub. They see a monster truck rally on TV and Harley mocks the people watching it. As they are driving away, a giant monster truck drives them off the road. Later on, they have to siphon gasoline from an abandoned RV. However, it is revealed that the RV has a mutilated body inside and the RV is surrounded by truck tracks that form a pentagram. Adam sees the strange-looking driver and Harley urinates in the cab of the monster truck before they speed away. At a hotel, Adam and Harley wake up with roadkill in their beds; they find a hitchhiker named Sarah (Aimee Brooks) sleeping in the backseat when they get to the car. Sarah eventually has sex with Adam.
