After graduating school, Tatum and her mother's latest boyfriend, Ted, have begun a deeper relationship now that her mother has run off and left them both, but now it's moving to the next level: he's taking her to her first-ever swinger's party. Tatum experiences not only sex of a different kind than she's ever had before, but realizes there's something beyond normal sex to get excited about as she gets double-door action that she's never known and finds that swingers have a whole new way of looking at sex that makes life so much more interesting for all involved.
