Ricki Rendazzo, an aging and struggling rock-and-roll musician living in California, is working as a cashier at a grocery store and fronting her cover band, The Flash. Her life of gritty bars and modest lodging is a far cry from the suburban family life she abandoned decades ago in pursuit of musical stardom. Her boyfriend and bandmate, Greg, gently tries to ground her, but Ricki remains stubbornly devoted to her fading dream.Her stagnant routine is abruptly shattered when her ex-husband, Pete, tracks her down with an urgent plea. Their
estranged daughter, Julie, is spiraling into a deep depression following a brutal divorce, having been abandoned by her husband. Pete asks Ricki to drop everything and fly to Indianapolis to comfort their emotionally devastated child. Reluctantly, Ricki agrees, though she is entirely unequipped for the upper-middle-class environment she once fled.Upon arrival, Ricki is met with open hostility. Pete’s polished, conservative new wife, Maureen, tries to play the peacekeeper, but Julie’s brothers, Daniel and Josh, are equally resentful of Ricki’s sudden reappearance. Julie herself is a mess—disheveled, suicidal, and bitterly angry at the mother who chose a microphone over motherhood. Ricki’s attempts at comfort are clumsy, defined by her bohemian sensibilities and unfiltered edge.Instead of playing the traditional matriarch, Ricki decides to help Julie heal in her own chaotic way. She takes Julie to a local salon to drastically makeover her appearance, blasts loud music, and coaxes her daughter out of bed. Slowly, beneath the friction and past resentment, a fragile bond begins to form between them. Julie realizes her mother is just as deeply flawed as she is, while Ricki is forced to confront the wreckage of her past choices.The emotional climax arrives at Daniel's high-
society wedding. Ricki and Greg fly back out to attend as guests. Ricki is initially excluded from the family photographs and treated as an embarrassing outsider by Maureen’s snobbish friends. Feeling alienated and unwanted, Ricki packs her bags, intending to quietly slip away before the reception.However, Julie intervenes, begging her mother to stay. Moved by her daughter's plea, Ricki takes the stage with The Flash, hijacking the wedding band's equipment. She delivers a powerful, heartfelt performance dedicated to Julie. Pete, watching from the crowd, finds a renewed appreciation for his wild ex-wife. The family is ultimately reconciled through the healing power of music, and Ricki returns to California with a renewed sense of connection, having finally bridged the massive chasm between her rock-and-roll ambitions and her maternal obligations.
