Chattuli unfolds deep within the untouched forests of Attappadi, where silence hides stories of pain and redemption. The film follows an unlikely bond between a blind elder ‘Maari’ – played by Jaffer Idukki and a teenage boy ‘Kannan’ – played by Karthik Vishnu, two souls brought together by fate and their shared thirst for revenge. Chattuli explores the thin line between justice and mercy, and the strength it takes to find light amid darkness.
