The storyline of the film is loosely based on D. H. Lawrence's 1928 novel Lady Chatterley's Lover though there are significant differences in plot and characterization. The story concerns a young married woman, Soudamini (Sheela), whose upper-class husband (P.K. Abraham) has been paralyzed and rendered impotent. Her sexual frustration leads her into an affair with the servant, Rajasekharan (Jayan). She eventually gets married to him but later discovers that he has had relationship with many ladies and he aimed only at her wealth. She and her only daughter Baby (born from her first husband) are helpless as they are not able to put him out of their lives. Later, a young man named Prabhakaran, who is the son of an ex-servant of Soudamini, enters their life and helps them to get rid of Rajasekharan. In the climax, Rajasekharan is shot dead by Soudamini.
