Dipper and Mabel are headed home from their college in Florida when a crazy driver nearly runs them off the road. Upon meeting the large truck again, they discover the sinister truth of the motorist, and struggle to escape with their lives. Basically Jeepers Creepers, but with the Pines. (This one seems like it'll be big on copyright, so I just wanna say right now that I DO NOT own Jeepers Creepers or Gravity Falls, although you probably already know that. Just had to get it out there before someone sues my ass...)
