Bale Pandiya (Sivaji Ganesan) is a young man who leads a troubled life. He is continuously being chased by Marudhu (also Sivaji Ganesan) - a look-alike of him and Marudhu's boss Kabali (M. R. Radha), who would be given a lot of money if they killed Pandiya. While being chased by them once, he gets into a runaway car being driven by an insane young girl(Vasanthi). The car crashes, but the girl gets cured from her insanity. Her father allows Pandiya, who is homeless, to stay with them. Parallelly, Pandiya falls for Geetha (Devika) and her father Amritha Lingam (also M. R. Radha) accepts the romance. But Marudhu and Kabali's pursuit for Pandiya still continues, and they successfully toss him into the sea. What happens to next forms the remaining story.
