Netrikkan (1981)

This provocative drama delves into the dark side of the human psyche through the life of Chakravarthy (Older Rajini) who is a successful textile businessman in Coimbatore. He is a great womaniser (perhaps his only weakness) and picks up any woman he wants. Apart from his dark secret he consummately portrays the image of a happy family man, living with his wife Meenakshi (Lakshmi), his son Santosh (also Rajini) and his daughter Sangeetha (Vijayashanthi). However, It doesn't take long for the observant and intelligent Santosh to come to know of his father's predatory nature and begin attempts to mend his father's ways. Radha (Saritha) gets introduced to Chakravarthy as a candidate for PRO (Public Relations Officer) interview and eventually gets selected and is sent to Hong Kong for training. Chakravarthy unable to tolerate his son's growing menace also sets off to Hong Kong for a vacation. Here he meets Radha and at one point ends up raping her. Chakravarthy flies back to India where he is met with a number of changes which all points out to the new General Manager. This person turns out be Radha who has joined with Santosh to teach Chakravarthy a lesson for lifetime. Can Santhosh team up with Radha to get Chakravarthy on the path to redemption?
