After the suicide of the teenager Allen Clark, his family decides to move from Chicago to the quiet Cradle Bay Island seeking a peaceful life for the siblings Steve and Lindsay Clark. When Steve joins the local high-school, the outcast Gavin Strick befriends Steve and introduces his also rejected friend Rachel Wagner to the newcomer. Gavin exposes to Steve in the refectory the punks, the nerds and the different tribes of the school and he defends the weird theory that a sinister force changes the behavior of the annoyingly perfect "Blue Ribbons", a group of good students that wear identical jackets and gather in the Yogurt Shoppe. Further he tells that he had witnessed the blue ribbon Andy Efkin killing their schoolmate Mary Jo that is missing and the local Officer Cox covering the murder. Steve does not believe on Gavin words, but when his friend is submitted to the treatment of Dr. Edgar Caldicott and immediately changes his behavior, joining the Blue Ribbons, Steve and Rachel ...

Decent late night fun
7 September 2006 | by See all my reviews

I caught this film on a late night TV slot (around 1:00). Since it was an evening of surprisingly watchable movies up until then (Michael Chrictons 'Runaway' & Clint Eastwoods 'White hunter, black heart') this mix of teeny horror and x-files type paranoia sci-fi was just the kind of icing on the cake I needed before finally calling it a night.

Even though it obviously suffers from some plot holes and studio interference, I must say that I still found it much better than other late 90's 'Scream' influenced (and included) teen horror revival stuff. Sci-fi element was, even though lacking in any deeper explanation, believable enough, especially the part with problems arising due to puberty related hormone/neurotransmitter surges (i.e. Lorna's sexual turn violent outburst at Steve's house) etc.

All in all, not really a shining example of cinematic art but still bearable enough for a late night entertainment.
