Delphine Dixie arrived on time for her first dental appointment and Doctor Brian Gaines was forever glad she did. Young and nubile, Delly was an instant temptation.
A chance encounter at a dental convention leads Brian and his wife, Kayla, to have an intimate conversation in which they admit who else in their lives they find attractive. Kayla mentions Chris, the handsome cosmetic surgeon who shares office space with Brian and a constant thorn in her husband's side, and Brian confesses to Delphine. Nothing comes of their talk until Delphine's next visit where she takes flirting too far. Brian tells an angry Kayla what happened.
What's good for the goose is good for the gander, thinks Kayla, and prepares to serves Brian a taste of his own medicine. Brian endures an agonizing night at home while Kayla goes to dinner with Chris. While her intention was only to make her husband jealous, the night, and Chris, turn out to be far more than she expected.
Kayla's return home starts an avalanche that rumbles through every aspect of their marriage, sweeping Delphine, Brian, Chris, Kayla, and many others down the mountain and altering the course of their lives forever.
