The world's only rat-free zone is about to be invaded by a contrary man with a mission. Wyley McFadden, ex-fertility doctor-turned-urban trapper, has launched an outlandish scheme to redress geo-zoological discrimination in Canada. In what looks like an ordinary camper van, McFadden is transporting a contraband cargo from Toronto to Alberta. But just past Wawa, he spots a female hitchhiker in a mud-encrusted tennis outfit. As McFadden gets closer, he realizes she is being eaten alive by mosquitoes and black flies. Fearful, starving and exhausted, the girl doesn't seem to know where she's headed and refuses to explain how she came to be hitchhiking in the middle of nowhere, warding off his questions by asking him about his own past. But once McFadden reveals his secrets, including the reason for his journey, she launches into her own shocking and terrifying story.
