Computer Beach Party was the name of an actual movie, the synopsisof which on IMDB reads as follows:

Greedy locals are trying to turn some beach property into a tourist attraction, and a computer expert sets out to use his knowledge of computers--along with the help of several local "beach bunnies" -- to stop them.
The film is from 1987, so what you're looking at here is basically the best weirdo computer movie in history, at least before Sandy Bullock's The Net ...or Jesse Bradford's Swimfan.

Eh, who are we kidding? All computer movies are the best! But this one's got the eighties in it!
