Rajarathnam is a rich man who lives with his sister Sarasu and a young house maid in
Madras. His sister arranges a marriage for him with Gayathri, a sixteen-year old who lives in
Tiruchirappalli. Soon after they marry, Gayathri moves to Rajarathnam's house and realises that the family has dark secrets. Rajarathnam is actually a
blue-film producer – he secretly records himself and his new wife in their bedroom scenes without her knowledge, and sells the films in the black market. Gayathri initially gives Rajarathnam the benefit of the doubt, but later discovers that Rajarathnam is already married to another woman, who is now insane.
Ganesh, a friend of the writer Chellappa, tries to free Gayathri from the hands of Rajarathnam. == Cast ==
