“Prey for Rock and Roll” delivers Gina Gershon in a smashing performance as Jacki, a no-bullsh*t rocker struggling to keep herself and her band together. Despite her wicked wit and undeniable sex appeal, Jacki fears that getting older will end her career in the image-driven world of rock. Jacki and her bandmates Tracy (De Matteo), Faith (Petty), and Sally (Cole), survive it all: dangerous sex games, a loveable ex-con (Blucas), internal friction, and industry slime balls. Through it all — they are unstoppable.
