Lovers Sethu (Kamal Hassan) and Nandhini (Rekha) commit suicide by jumping off a cliff. But when they jump together, fate conspires to keep Sethu alive while Nandhini plunges to her death. A devastated Sethu is counselled by his uncle Chaplin Chellappa (Kamalhassan) against attempting a second suicide but turns into a quiet, moody recluse. On the anniversary of Nandhini's death, Sethu runs into Malini (Rekha) at the same spot where Nandhini died and dissuades her from committing suicide. Malini falls in love with Sethu and enrolls in the dance school where Sethu is working as a teacher.
