Here's what this is...
It's quite simply an absolute no-budget, spectacularly failed attempt at a comedy; you might expect to see Lorenzo Lamas in something like this, but not Mischa Barton. I have no idea what happened to her career, it's not like she's been in anything decent for a while, but this has to be an all-time low.
It comes across as a reality show of a beach house where a bunch of young forgettable guys try to spy on and/or shag a bunch of semi-hot girls running around in bikinis. Some of them are topless in a few scenes (not Mischa though, obviously), but it's really not worth it even for that. The script and acting is actually so god-awful that it would be more entertaining if it was a reality show.
It defies belief. An utter waste of time, and I have no idea why it even exists.
IMDb-boards would be less confusing if people would mark their signatures clearly.
