Diane and Ken love each other lots and lots.  But it's Diane's birthday and she wants to try something new and exciting.  Mark thinks things are just fine the way they are.  Therein begins a tale of sexual and emotional exploration that eventually leads the couple on a trial of deception, distrust, infidelity and abrupt reassessment.  Tony Tedeschi plays Jake, Ken's (Mark Davis) best buddy and chief co-sneak, eventually winding up in a lesbian strip-club's bathroom watching the chicks get it on and being glory holed and more by one pretty switch-hitter.  Of course, the traditional double standard means that's different from Diane (Misty Rain) dabbling with lesbianism in the form of the more dominant Nikki Sinn, who's stretching the definition of an "open relationship" in her own home.  Not exactly a "how-to" film on exploring alternative sexualities, but a nice variety of sexual situations, some great sex, good acting and sets.  Hopefully Diane eventually learns that she doesn't have to decide if she's "one of them or not" because there's this neat thing called bisexuality.
