The In Crowd (2000)

This isn't some dumb teen thriller; there are tits here! As if that wasn't enough, there is an innocent-yet-zipper-tickling performance from Lori Heuring, who plays Adrien, a college student who takes a summer job at a ritzy country club. But every sweet ingenue needs a bitch to play against, and it's hard to believe anyone playing rich-bitch Brittany better than Susan Ward. At first all is well and Brittany teaches her new friend the rich-kid ropes, graciously introducing Adrien to her inner circle. But when Adrien starts dating a guy Brittany likes, the claws come out and the kitty fur flies. Reeeeeear! The fun plot is just one reason to see this flick. Let's see, what do hot girls on summer break do? Oh, yeah, bikini-clad beach frolicking by day and drinking like fish at night! Any questions?
