Kate is a vibrant, sensual creature, brimming with needs. Her husband Daniel is a cheating rat, driving her crazy with his infidelities. The one thing she can rely on is her music, and she plays the viola like a wild goddess. When the orchestra she's a part of embarks on a tour of Europe, joined by a dominitrix diva and a bass singer whose voice is so low he is known as the human vibrator, Katie is soon experiencing life to its hedonistic limits. While she is carefully recording each passionate encounter in her journal, another member of the orchestra is writing down his. Intrigue begins when the tow books are inadvertently switched. And if the truth gets out, they'll never play a concerto in their home town again!
