After joining up with a gang of surfers and their lifestyle, a woman fears that the serial killer running rampant through the group may be herself when she falls victim to a split personality and tries to stop it from continuing before all of her friends are killed.This was a pretty decent mixture of 60s Beach movie and slasher, though the fact that the stalking scenes are non-existent and never developed while the beach-party aspect of the movie is allotted full time to develop and go through it's paces clearly shows the slasher angle is just that, an angle used to give it a bit of individuality and distance itself from the pack.
