R. exposing him in his newspaper, harasses Saro, egged on by his avaricious mother (Y. Vijaya) and sister (Bhuvaneswari). The burden of taking care of the family becomes a little too much for Roja. Finally T. R., against all odds, advises Roja to accept Murali's love.

Production

After failing to find a suitable lead actress to appear opposite Silambarasan, Rajender postponed the project and started to make Sonnal Thaan Kaadhala. Bobby, actress Rajashri's sister, was cast in a leading role, but the actress opted to work on other Telugu films instead. Subsequently, her role in Sonnal Thaan Kaadhala was shortened, as Rajender continued to shoot without her.

Reception
Visual Dasan of Kalki wrote poignant romance, warm sentiment, menacing sets, these elements make a typical Rajender film. this one is a mixed bag which seems to have mistakenly copied his own style. Although the film was an average grosser at the box office, the soundtrack was somewhat a success. The film won two separate awards the following year; a Tamil Nadu State Film Award and a Filmfare Award.
