Dawn (Jess Weixler), a sexually repressed teenager who is unfamiliar with her own body, starts to realize that she's different from other girls. When her and her boy friend Tobey go to a nearby lake to swim he rapes her--and finds out that she has teeth where there shouldn't be any teeth. He falls into the lake and they later find his body. Dawn, meanwhile, makes her first trip to a gynecologist to confirm her suspicions. Of course, the doctor is slimy (he doesn't use latex gloves when examining her) and deservedly gets a few digits nipped off.
The biggest strength of this film is Jess Weixler's performance. She's going to be a great actress to look out for.
On one hand this is a serious coming of age movie but it's also a dark comedy and a horror movie with plenty of bite. If you're a guy you can not help but cringe.
