Born to Be Bad

The plot: A spy is sent to blackmail a man who works at some vaguely-defined government lab. He decides to get a female friend of his out of jail, so she can seduce the intended target. Now, since the target is already bonking everyone in reach, this seems superfluous. However, he gets her out, by sleeping with the female warden in a very boring sex scene. The girl gets out of jail, and successfully seduces the target. A little too successfully, as they fall in love. However, the spy is also in love with the girl, and he instead blackmails his handlers into letting the girl live happily ever after with her former target.

All in all, a fairly good pornographic film.
