Kasu (film)

Karan arrives in Kerala with his best friend Sandy to meet the businessman Dileep. At his office, the employees tell them that Dileep is abroad and the two friends decide to stay in Kerala until his return. Karan then comes across Prarthana on multiple occasions and they eventually fall in love with each other. Upon his return, Karan meets Dileep and Dileep refuses to help him. Karan discovers that Prarthana is Dileep's sister. Dileep proposes Karan a deal: either Karan marries his sister without any dowry or Karan takes a huge sum to let go of his sister. Karan surprisingly accepts the money thus breaking Prarthana's heart.

In a flashback, Karan lived with his mentor Viswanathan and his daughter Thulasi. At Thulasi's engagement, the groom's family asked for a huge sum of money and Viswanathan reluctantly accepted. Viswanathan planned to withdraw a property case in Kerala and to take the money so he requested Karan to go to Kerala and to solve the issue.

Back to the present, Karan returns to Chennai with the money to pay the dowry. The day of the wedding, the groom's family ask for more money and the wedding is eventually cancelled. The circumstances force Karan to marry Thulasi on the spot and Viswanathan died of a heart attack that day. Thereafter, Karan becomes a wealthy businessman while Prarthana is diagnosed with depression and has lost all her memory. To cure his sister, Dileep begs Karan to come to the hospital and a remorseful Karan secretly meets her at the hospital. Later, Prarthana regains her memory but the doctor warns them to not mention Karan's marriage. When Thulasi learns of it, she decides to sacrifice her life and attempts to kill herself with sleeping pills. At the hospital, Thulasi is saved and Prarthana realises that Karan sacrificed their love for the good of a family. Prarthana praises Karan for being a genuine person and she accepts her fate. The film ends with Karan and Thulasi hugging each other.

The film began production under the title Uravukku Mariyathai and was completed in the late 1990s but it remained unreleased for unknown reasons.[3] After the surprise success of Uyir (2006) starring Sangeetha, the producer and the director prompted to release the project.[4][5][6][7]

The film score and the soundtrack were composed by V. S. Udhaya. The soundtrack features 8 tracks.[8][9]

Following the rising status of actress Sangeetha after Uyir (2006), the producer and the director took efforts to get the film released which had been in the cans for years.[4][5]

Indiaglitz wrote, "Both Sangeetha and Rehman have come up with good performance. Sangeetha, who looks younger, plays the role with ease" and concluded that the film was a disappointment.[6] Malini Mannath said, "A weak screenplay, uninspiring narration and some lacklustre characters and performances make 'Kasu' a film better forgotten".[7]
