Kin (2023)

Growing up Mell wished her autistic brother could speak - now, in adulthood, she realises you don’t have to talk to explain what you need. KIN is a coming of age story between two sisters (Mell and Janine) and their neurodivergent and autistic brother (Carl), exploring sibling relationships, family duty and care.

Unfortunately the movie Kin is not yet available on HBO Max.
