is a reward) is a 1987 Indian Tamil-language drama film, directed by Visu and produced by Kavithalayaa Productions.

[1] The film was remade in Kannada as Krishna Mechchida Radhe and in Telugu as Srimathi Oka Bahumathi.

Meanwhile, Rajeswari, a middle-class woman, living with her daughter Karpagam, receives an eviction notice to leave her house.

Sathyamoorthy who works in the same office asks a bribe of three thousand rupees to Rajeswari, in order to delay the eviction case in court by a couple of years.

After they are evicted, Balaraman feels sorry for them, and asks them to stay in a nearby temple, and visits both mother and daughter regularly.

He discovers that Rajeswari's illiterate husband (who died recently) was cheated by his three brothers into giving up all his wealth and property.

Unbeknownst to anybody, Uma registers the house and property to her two brother's names, as she feels it's the right time.

Uma also tells Namachivayam that she has been putting three hundred rupees in the bank every month on her brother's names as rent money, ever since the day she got married, so that in future if anybody in the family or society raise any unnecessary concerns, she will be able to show the rent money.

Uma asks Krishnan to marry Nandhini immediately, as it is considered sacrilegious for a boy to kiss a girl before marriage, as per Indian tradition.

When she arrives, Naadhamuni acts as if he is having an affair with the servant maid Aandaal, in order to irritate Nandhini and make her return.

While Nandhini and Krishnan regularly fight at home, Balaraman tries to complain to government officials about Sathyamoorthy's corrupt practices.

One day Krishnan decides to start a business, and Nandhini shows interest in helping him, and they slowly sort out their differences.

Karpagam uses Balaraman's fifteen thousand rupees from the rent money given by Uma, to buy a plot of land duped and sold to her by Sathyamoorthy.

On the same day, anti-corruption officers go to Balaraman's house to arrest him for possession of bribe money.

Karpagam realises her mistake, and decides to lock herself in her room as a punishment, for as long as Balaraman is imprisoned.

Thirumathi Oru Vegumathi marked the cinematic acting debut of M. S. Bhaskar, who was previously a theatrical actor.
