Ten years. Five women. One concert.

Your reunion was never this good. Or this complicated.

A decade ago, Callie Smalls walked away from her top-selling, all-girl music group to pursue her solo career in fashion and television. The other four members—Angie, Tabitha, Mandy, and Daphne—were left high and dry, scrambling to move on from a life of recording studios, worldwide tours, and everything that goes with fame and fortune.

Following her stint hosting the acclaimed reality TV show, Made for Me, Callie realizes that the only way to boost her fading career is to book a one-night-only reunion gig at a major music festival. Without talking to her former bandmates. Scattered across the country, at different points in their lives, can they come together to rekindle the magic in their music?

A soccer mom whose husband doesn't know about her past. A fading star, sacrificing all to stay in the spotlight just one second more. A party girl, challenged with her most important role yet. A tiger mom, fighting for her son. A desperate woman, unhappy and alone.

A lot can change in the course of a decade. Will it be harmony or hatred for the Sassy Cats?
