Set in Middle America, a group of teens receive an online invitation for sex, though they soon encounter fundamentalists with a much more sinister agenda.
 
This movie is a complete departure from Kevin Smith's early work.  It's very creepy and shows that Smith has more range than just Jay & Silent Bob.  There is action, suspense and plenty of WTF moments scattered throughout.  That being said, the story does kinda fall apart at the end, so be warned.  
 
FUN FACT:  Kevin Smith: Smith has a quick off-camera cameo at the end of the film, as a prison inmate, yelling the last line in the film.
