Part of an emerging queer cinema from South India Kattumaram tells of patriarch Singaram and his orphaned niece Anan, fisher-folk survivors of the Tsunami. Beautiful Anan teaches in the local school and has many fishermen interested in her, but Anan instead secretly falls for a new female supply teacher. As Singaram finds out and tries to come to terms with this revelation, gossip about the young women's relationship quickly spreads. Singaram is left facing the choice of either defending his beloved niece and her partner, or giving sway to the demands of an angry community.
