"Here and Now" follows Vivienne (Parker), a jazz vocalist in New York City, who lives her life for herself and for her art. After she receives a diagnosis that shatters her world, we follow Vivienne over a compressed 24-hour window as we see her prepare for an upcoming world tour, navigate her relationships and familial obligations, and reflect on her life's successes and failures. With the support of her worried mother Jeanne (Bisset) and ex-husband Nick (Baker), Vivienne strives to make peace with the city around her.
