In a big Tamil city of the 60s, Muthu (MGR), a tramp with a good heart, falls prey to a blackmailer named Djambhu (S. A. Ashokan), a gangster who hides his fraudulent activities behind his respectable profession of a director of cabaret.
Forced by Djambhu, Muthu steals for its account and especially to save its beautiful Geetha (Jayalalitha), another victim of Djambhu's blackmail.
Dancer's story occurs in the establishment of Djambhu.
Coming upon a quarantined city, Muthu comes face-to-face with Shanti (Sowcar Janaki), a young widow bullied and left for dead by her obnoxious family-in-law.
