Mouna Ounth Mukhar Hriday (Silent Lips and Murmuring Hearts) is a tragic love story set against the backdrop of an Arunachal Pradesh going through a process of transition.
Rinchin and Yama are two star-crossed lovers coming form different tribes who happen to meet during the construction of a road from Sakuto Bomdila. Rinchin is a bold and daring Sherdukpen youth while the beautiful and affectionate Yama is a Bangni girl.
Limited to the precincts of their own domains the tribes initially view each other with suspicion, Dilip Saikia, the field assistant for the construction of the road, takes particular care to bring together the tribes. He sees his mission to be not merely the construction of a road but to build bridges across the diverse tribes so that all their misgivings regarding one another could be done away with.
The process of lovers coming together is paralleled by the process of the gradual convergence of the two tries as they come to believe and accept that they are really people belonging to the same human race with merely superficial differences of clothes and customs.
