Rite of the Shaman (2022) on Netflix

Plot summary

Kai cannot speak. He is a high school student who looks after his mother, and he finds calm in nature and in memories of his grandfather, a shaman who has died. He must follow in his grandfather's footsteps, since he was meant to become a beacon of light. Two things press on him: life at home, and a bully at school who intimidates him. The strain of it leaves Kai depressed, and he pushes the loved ones around him away. He faces a decision: whether to continue down a dark path, or to follow his grandfather's wisdom and embrace his destiny.
