At Vancouver airport, a distraught young man wanders into a car rental agency, carrying a backpack full of beer and boxer shorts. Trevor is in the midst of a serious crisis. His all-too-comfortable existence as a wannabe filmmaker has been disrupted by a phone call from his Czech girlfriend. In an attempt to get over her, Trevor rents a Dodge Neon and blazes down Highway 99, heading for California. But his journey is fraught with peril, and all he has for protection are a semi-automatic pistol, his trusty plastic visor and a fractious flea-ridden cat.
