Nancy, an Indian-descended mother, returns to her hometown and opens a sign language school while caring for her son Ajay, who lives with both hearing impairment and a neurological condition. Among her students are Mina, a Malay girl determined to become a Muay Thai boxer despite cultural expectations, and Sansan, a Chinese girl deeply bound to the ocean she loves. Along the vast coastline, three families and three children navigate faith, identity, and freedom, until their intertwined lives become a moving symphony of resilience and love.
