Continuing the story of the first film, Jaari 2 follows the journey of Namsang and his wife Hangma as they embark on a new chapter of their married life. The film's narrative is deeply rooted in the culture of the Limbu community and revolves around the Chyabrung, a traditional drum that symbolizes love, identity and resilience. The film explores how Namsang navigates personal struggles and the complexities of his community's traditions with the guidance of the drum's rhythms.

The central characters of Jaari are Namsang and Hangma, a married Limbu couple. After a brief argument with her spouse Namsang, Hangma chooses to leave him by giving back his Yuparung (a sacred coin). She then marries a different man after falling in love with him. The jaari is claimed by Namsang and his family, but Hangma’s family refuses to pay, forcing Hangma into slavery in Namsang’s household until the jaari is paid.
