Maddy Baker is stuck in her personal and professional lives. In addition, the mysterious song she's had stuck in her head since she can remember is on a loop and driving her crazy. One day, her BFF Liz invites her to the opera, and lo and behold, she hears "her" song. It triggers a journey back in time to another lifetime, to Revolutionary France. At first, she thinks she's in some weird dream, as most of the people she knows in the present also exist in the past. Who she doesn't count on meeting is Jean-Loup, an idealistic painter in an increasingly chaotic world, as the Reign of Terror is established against the "enemies" of the fledging Republic. Maddy realizes that she is actually getting a second chance to redeem herself from this life as a frivolous courtesan, and finds herself on a hazardous journey where she encounters true love and self-fulfillment.
