An outright boring and bizzare movie of catastrophic proportions. The original name is "Hamos sto aigaio", and it was also called "Blown Sky High" and "Sky High" - the "girl" in the title (it's been released here as Sky High Girl) was added purely to position this as a soft-porn flick.
About the storyline, what we have is a scientist who has invented a hallucogenic sound modulated tape, aimed at helping cure mental stress. But if it were to fall in the wrong hands, in this instance the KGB, it could be used to create havoc in the world. Overcome with moral guilt he decides to get rid of his invention. In the process of doing so, he gets killed. But not before giving the tape to his trusted friend, who is instructed to deliver it to a fellow scientist in Greece.
Here steps in our hero, Les (Daniel Hirsch), who is an American computer nerd. He, along with his friends Bobby and Mick, is on vacation in Greece. As fate would have it, Les bumps into the late scientist's friend who somehow manages to palm off the tape to him just before being shot by the supposed KGB. At this point the movie gets even more complicated.
With the KGB in hot pursuit of Les and his friends, begins a boring chase-and-run saga that never seems to end. Suddenly out of the woodwork emerges a certain Mr. Simon Boswell from the American embassy, who tries to help the trio in trouble. In all this confusion Les, Bobby (Clayton Norcross) and Mick (Frank Schultz) find time to experience true love. The female cast has no relevance to the plot except to look pretty.
Just when you think you cannot take any more of this movie, it thankfully ends, because Mr. Simon Boswell is in reality a CIA agent trying to procure the tape to sell it in the blackmarket.
The only redeeming aspect of the movie is, believe it or not, the cinematography. The scenic shots of the beautiful Greek locales are a sight to behold. But it still remains an intended comic-mystery movie, which will leave you wondering what mysterious force made you sit through it.
