The 1970's was known for the drive-in sexploitation films. This one is just right for anyone who is nostalgia oriented. It's one of the few before "Meatballs","Little Darlings", or "Porky's". But in return, it's before the time of slasher films. So there's more sex, than comedy. And a touch of drama to go along with. Here you have four beautiful women, along with a cousin who work at a camp, meeting different people. Making love. Having fun. Pure and simple. However, that fun is about to come undone, when a mysterious figure starts killing people. One blonde was being chased by a biker who decided to stay behind at the party. She only met her end by a female figure with a knife. Then more victims are killed in different matter. A water skier is sniped by the same person. But after all what the ladies have been through, they managed to have a fun summer. Seems like anything or everything goes in that place. This is a cult classic that should be recognized by movie goers. It's a mixture of sex, intrigue, and surprise. I like it very much. 3 out of 5 stars.
