A 34-year-old nurse experiences a variety of flu-like symptoms. None of her doctors are able to discover the cause, until she visits the gynecologist for a routine check-up.

In the end, science was able to determine not only how she had been infected, but also by whom. The worst part: it wasn't an accident. (thetvdb.com)
