High school senior Joan's car is a death trap, college admissions aren’t calling, and her well-meaning parents’ only advice is to “pray on it.” So she does. And then Joan of Arc shows up. Yup, that one: saint, warrior, and deeply unimpressed spiritual guide. She delivers human Joan's divine calling--not to lead an army or save a nation, but to rescue the gilled residents of her pet store job: betta fish. What begins with confusion, doubt, and frantic Googling (“are betta fish important?”) spirals into a full-blown sit-in protest as Joan tries to save the oppressed aquatic creatures from their terrible pet store conditions, all while tackling the idea that purpose only matters if it’s big/impressive/profitable. With Joan of Arc at her side, she learns to trust her instincts, stand her ground, and defend a calling no one else takes seriously.
