Untogether (2018)

Andrea is a recently sober writer whose career has stalled since she published her debut novel several years ago. She strikes up an affair with Nick, a doctor-turned-writer who is hailed for his wartime memoir. At the same time, her sister Tara, a massage therapist dating an aging rock star, finds herself inexorably drawn to a newfound religious zeal and, particularly, to a politically-engaged rabbi.
