Beautiful Maggie Mae Williams, a singer in a country-rock band from Boston, is an aspiring bluegrass mandolinist. While on a trip to New Orleans to visit her former college roommate, Maggie meets Zak Robichaud and Justin Boudreau, two musicians in the Cajun blues/rock band the Bayou Blasters. Maggie quickly falls in love with Zak, the dazzling lead guitarist. Despite her parents' reservations and a warning from Zak's ex-girlfriend Jacqueline, Maggie moves in with Zak and Justin into their bungalow near Lafayette, Louisiana. They begin music careers that lead to success beyond their wildest dreams, Maggie with her bluegrass band Little Maggie, and Zak and Justin with the Bayou Blasters. But Maggie and Zak find it difficult to balance the demands of their careers with those of their personal lives. As the pressures of touring start taking their toll, Maggie finds herself increasingly attracted to Justin, the steady and reliable bass player who is able to offer her emotional support when she needs it the most.
