Hayley Swift, a country music diva who has slipped out of the limelight, gets more attention when she's mistaken for Taylor Swift's mom than for her former glory days. When she's invited to perform at her 35th high school reunion but a bus accident puts her back-up singers in a hospital, Hayley begs her long-gone-domestic quartet from high school to join her onstage for the gig. They're such a hit that she invites the women to fill in on a low-budget tour for a couple of weeks while her singers recover. Thrilled at the chance to flee routine for a dream deferred for decades, the friends readily accept.Nefarious flirtations, indiscriminate mood swings, equipment malfunctions, and a few nasty cat-fights combine to wreak havoc on the Retro Rodeo tour, but it's a crazed stalker, an overzealous fan, and an unexpected pregnancy that ultimately derail the road trip. In the midst of the mayhem, friendships and fantasies are redefined as the women come together to face one's debilitating illness. True love emerges from the tragedy, though, and the friends discover new strengths and aspirations as this adventure ends and new ones begin.
