Blue Sky) is a 1965 Indian Tamil-language film, directed by P. Madhavan and produced by Varathan.

Babu has the tendency to use hitchhiking as his transportation method to reach his workplace, Shanthi Theatre.

They meet every day, and they fall in love, and Babu tells her that they can only marry if he gets a good job for his qualification, a Bachelor of Arts.

Somanathan, a paper mill owner, asks Sharma to look for a groom for his only daughter, Gowri.

Babu informs Vimala that he got a job in Somanathan's paper mill, and then she introduces him to her father Varatharajan.

Gowri is afraid of injections and surgery; she hides her stomach pain, but her mother notices her suffering, and they get her to the hospital and find that she has uterine cancer, which can't be cured.

As Gowri hears that she has been rejected by Prakash's family, she is sad and disappointed, which Babu notices, and he tries to make her feel better, but she ends up proposing to marry her.

Babu is shocked to see Vimala at the office, and she threatens him by saying she will reveal their past relationship to Gowri.

The lady doctor checks and informs Babu that Gowri will only live for four or five months, so let her be happy, making her believe she's pregnant.

She tells him to marry Vimala, and she gives him the baby doll, which she considers their own child, while taking her last breath.

On the road, Vimala finds Babu with the doll, and she begs that she understand his innocence, but he walks away.

[7] T. M. Ramachandran of Sport and Pastime called it a "poor film" and criticised Madhavan's direction as "naive".

He also noted "There is nothing much to write home about K. Balachander's screenplay and dialogue" but called Viswanathan's music "pleasing".
