Mann is set in northern Sri Lanka in the early 80's - a country that was in the process of descending into a fully-fledged ethnic conflict. The present day civil war scenario was not in evidence. The village was idyllic, primarily agrarian and peaceful on the surface. The arrival of a Tamil family from another part of Sri Lanka opens the underbelly of feudal village life bringing into play long established prejudices and customs.
A man (who) returns to the village where he grew up after 18 years. On the journey to the village, he remembers his life as a teenager growing up in a social environment of strict structures of class and caste. A carefree school life, coming of age pranks and sexual awakenings. He is soon involved in a complicated emotional situation where love, lust, obsession and betrayal ultimately lead to tragedy.
