adam ( eric jungmann ) and obnoxious best friend harley ( justin urich ) be drive cross country to a wedding . along the way they pick up sexy hitchhiker sarah ( aimee brook ) . then and for no reason and a monster truck keep try to run them off the road . and maybe kill them . who be do this and why . pretty good horror film . it energetic and full of flashy direction which get you right into the action . it also a horror comedy . most of the humor be infantile and really gross but actually somewhat funny . also this movie really pile on the gore at time but that a good thing . the acting be ok jungmann overplay his nerd role a bit much while urich be stick with the hopeless role of the foul mouth and sex obsess best friend but pull it off while brook be good too in a limited role . but i could see the twist end come long before it happen and logic totally disappear at the end ( especially the rescue ) . still and this be a gory and sometimes funny and sometimes scary horror movie . i give it a 7 .
