When ten-year-old Daniela loses her voice after singing too passionately at a school event, the doctor prescribes complete silence. But as she struggles to follow the order, the adults’ confusion and passivity open space for her classmates to impose their own cruel sense of control. The debut collaboration between Cuban filmmaker Aria Sánchez and Brazilian director Marina Meira, ‘Primera Enseñanza’ (‘Primary Education’) transforms a simple act of silence into a chilling reflection on power, conformity, and the fragile loss of innocence.
