Poly Styrene was the first woman of colour in the UK to front a successful rock band, and a key architect of the riot grrrl and Afropunk movements. But the late icon didn’t just leave behind an immense cultural footprint. She was survived by a daughter, Celeste, who became the unwitting guardian of her mother’s legacy and demons. Misogyny, racism, and mental illness plagued Poly’s life, while their lasting trauma scarred the pair’s relationship. Featuring diary entries narrated by Oscar-nominee Ruth Negga, this documentary follows Celeste as she traverses three continents to better understand Poly as an icon and mother.
