A Dirty Story.

A group of friends listen as one man tells them a story about a time when, in a small cafe, he discovered a peephole into the ladies' bathroom and became addicted to looking through it at female genitals. They ask him questions and come to conclusions about sex. This is a filmed, scripted version. Then, the actual person who this happened to relates the same story; this time, however, it is an unscripted documentary, in which the same things occur as in the scripted one.
