A group of seven young adults party in a Mediterranean resort after meeting in a bar. They go aboard a yacht and sail into the ocean. But when one of them dies in a freak accident, the others begin to argue about what to do and a ruthless fight for survival begins. Three 20 year old girls hook up with four young men and head out to open waters to smoke Russian Ice and take pills. While they talk about kinky sex, the subject of Donkey Punch arises. I had no idea what Donkey Punch was and now that I know it seems to me to be terribly misogynistic. It is a sexual technique in a woman is punched in the back of her head as the male reaches orgasm in the doggy style position. Supposedly this causes the woman to have involuntary sexual spasms. (I understand that this is urban myth). The one “nerd” on board tries this with the blond female and she is accidentally killed.

Quite naturally chaos follows and a game of bumping each other off ensues. They either try to cover up the death or try to get away

The first half of the film is highly erotic with a great deal of female nudity and the sex, which in this case is straight anal, is unprotected. It is not what can be called a nice film but that does not mean it cannot be enjoyed. The actors are all capable which really means that they are no “great shakes”. Just when you think everything has calmed down, something chaotic happens. The script is very realistic but the movie as a whole is watchable but I do not think it will be memorable.
