So the heirs (and 50 of their closest pool partying friends) show up at this creepy looking mansion for the will reading at midnight. To pass the time until midnight they sing, swim in the pool, flirt and dance. During all this the evil lawyer has enlisted the help of some killers to try and murder the heirs in all kinds of horrible ways like axes, a hammer and even cutting in half on a giant saw! There's also a random gang of biker idiots who are easily the funniest part of the movie. When the leader, Eric Von Zipper, fell through that secret door I laughed for like 5 minutes.
For what it is...and I don't even know what it is...THE GHOST IN THE INVISIBLE BIKINI is kinda funny in a stupid live action "Scooby-Doo" kind of way. I imagine that 99.99% of the population would dislike this movie, but for whatever reason I thought it to be so dumb it's was funny. That said, still don't risk watching it on your own. Bring a friend.
Update: Well, I'm an idiot. I just figured out that this is one of the original "Beach Party" movies. It was suppose to star Frankie Avalon and Annette Funicello, but they passed and starred in FIREBALL 500 instead.
