Unni, a struggling film editor in Kerala, is editing a travel vlog. It shows members of a Kenyan tribe singing a traditional song. Unni’s grandmother overhears the song, starts singing along, and claims to know the song. Intrigued, Unni and his girlfriend Anupama share his grandmother’s song on social media. Realising from the comments that many people know the song, they set out to make a documentary about its origin. They travel across Kerala and interview people from various walks of life claiming to know the song. With each new person they meet, the mystery surrounding the song deepens.
