Becky Something is a '90s punk rock superstar who once filled arenas with her grungy all-female trio Something She. Now she plays smaller venues while grappling with motherhood, exhausted bandmates, nervous record company executives, and a new generation of rising talent eager to usurp her stardom. When Becky's chaos and excesses derail a recording session and national tour, she finds herself shunned, isolated and alone. Forced to get sober, temper her demons, and reckon with the past, she retreats from the spotlight and tries to recapture the creative inspiration that led her band to success.

嚐到成功滋味的龐克浪女，初紅乍紫的人生就此旋繞於藥物、酒精、怪奇信仰之中，墮入一道漫長的自我毀滅修羅道。她仍有話想說、她仍有歌想唱，但她狀態如此不穩，總伴隨不可預測的危險行為，粉碎事業夥伴的熱情，讓親近的家人傷心欲絕。她能否掙脫這一身混沌的傷痛，能否在巨星誕生自燃的餘燼中，再次綻放希望的光芒，捕捉生命的可能，搖滾愛重生。

《使女的故事》金獎影后伊莉莎白．摩斯和導演三度合作，詮釋出一個被環境和自身缺陷逼陷絕境的藝術家面貌，張狂無比的演出，令人過目難忘。緊貼角色的運鏡節奏、混亂緊張的搖滾後台細節捕捉、需要觀眾填空的斷裂敘事，影片除大幅度的情緒振盪外，末段角色那心若止水的描繪，更令人玩味。《唐頓莊園》丹．史蒂文斯、超模卡拉．迪樂芬妮、《水行俠》安柏．赫德亦助陣演出。
