The Bare Wench Project 2: Scared Topless(2001)

Four sorority sisters recently visited Bare Wench Mountain and disappeared, prompting five of their beautiful, busty chums to set out on a quest to find them. But problems -- and blouses -- come up when creepy things start happening in the woods. And the deeper the women go into the wilderness, the more scantily clad they become in this grisly slasher.
