After a post-date boff with Nick Manning, Xxxena says she is so happy cuddling just like this and Manning responds by saying he wants to see other people. Well! She takes off in a huff and gets into a car wreck. When she comes to, she sees fucking people. Or people fucking. Starting with Manning doing her best friend, winking at her while he does. Her doctor, after fucking his nurse, tells her that there's this experimental German treatment for her problem and after she sees the nurse and another patient doing it - with her joining in - in the waiting room, she decides to try it. The "German treatment" is der drei-way, mit der Looking-Glass on der Ceiling. After that, she's cured of her delusions and gets a mirror installed on her ceiling. By two guys, wink wink.
The is-she-dead-or-what? question never gets dealt with and becomes uninteresting after a while. Sex scenes are mostly overlit and slow. Xxxena is striking, though, and her presence might sell this tape.
