Riverdale is hosting the first ever GIRLZ ROCK festival in Pickens Park, with none other than JOSIE AND THE PUSSYCATS headlining. Also joining in the music mania is Betty, Veronica, and Jola Kitt's own power trio, ROCK CANDI! But when some of Jola’s old, rough-around-the-edges friends from her previous hometown decide to invade the festival and start a ruckus, they’re going to need extra help to get things under control. And even Josie and the Pussycats’ new head of security detail, Kip Burland a.k.a. THE BLACK HOOD, feels outnumbered. Fortunately, Betty and Veronica have a trick up their sleeve: they’re calling the VIXENS into action. But will the biker girls have what it takes to restore peace and get the concert back on track? Find out in this ROCK-TASTIC spectacular!
