Vishwanath Nayak, one of the eight producers, a chartered accountant for Arun Nalawade, a Marathi stage actor, suggested him to make a film. Later, Arun came across a story by writer Madhavi Gharpure, published in the Diwali edition of a magazine and thought that it would make a wonderful film storyline. The distribution plan for Shwaas was in place before production began. In the initial stages, it was taken to as many villages as the team could manage; marriage halls, school auditoriums and makeshift venues were all used for screening. All this despite the fact that Shwaas has no songs, heroes, heroines or recognizable stars of Marathi film industry.

• Ashwin Chitale (Parashuram Vichare, the child suffering from retinal cancer)
• Arun Nalawade (grandfather of Parashuram who takes him to Mumbai)
• Sandeep Kulkarni (Dr. Milind Sane who operates on Parashuram)
• Amruta Subhash (medical social worker named Asawari who helps grandfather, child and doctor to understand each other)
• Ganesh Manjrekar (Divakar: Parashuram's uncle who accompanies child and grandfather to Mumbai)

A villager (Vichare) brings his 8-year-old grandson Parshuraam (also known as Parshya) to a doctor in Pune to diagnose the child's eyes. They are accompanied by Parshya's maternal uncle Diwakar. On the first day Vichare is asked to sign the usual papers before admission in hospital. Upon asking, he learns that the papers say the doctor would not be responsible if anything goes wrong. Vichare, the rustic grandfather finds these terms unacceptable. A medical social worker, Aasawari, quickly comes in and explains the practice to Vichare. She calms him down and accompanies them during the first appointment with the doctor. Dr. Sane quickly diagnoses child as a victim of retinoblastoma — a rare retinal cancer. After consulting with other colleagues in US and UK doctor finds that only way to save child's life is to perform an operation that will leave the child blind. As per rule, doctor explains this and insists child be informed of this before surgery. He cannot be operated without this knowledge as it was against ethics. Aasawari (Amruta Subhash) who helps the doctor in convincing the grandfather and the grandson, tries to keep track of Vichare and persuades him not fall prey to other doctors promising false medicines. She tries to befriend Parshya to explain him what is going to happen. However, she finds it is too difficult to explain to him that he will turn blind.

The film then depicts the grandfather's struggle to accept the reality that the only way to save his grandson is at the cost of his eyesight. He tries to come to terms with the situation and his personal agony is shown in scenes, like taking second opinion, explaining his grandson the reality and his desire to show him everything possible before his grandson loses his eyesight. For some reason, the surgery has to be postponed by a day. That afternoon, grandfather and grandson disappear from the hospital ward and a frantic search follows. Confronted by an angry surgeon on their return, the grandfather states quite simply that he wanted to show Parshya the sights of the city for one last time.

Shwaas has been applauded for scenes which depict the difficulty faced by the doctors to explain to grandfather and Parshya that nothing can be done and the truth is but inevitable. It shows the medical fraternity in a very positive light, with the doctors and nurses being extremely supportive and doing the best they can, and helping the village with the best facilities. The last shot where Parshya returns home wearing dark glasses, waving to his family and friends from the boat was widely appreciated by film critics.

This Indian melodrama about a young boy with retinal cancer whose only chance for survival is an operation that will leave him blind is unstintingly sentimental and a bit tedious, but it also has a winning simplicity and some touching moments. The story is a kind that American audiences are accustomed to finding on basic cable television, and there is something strange and oddly gratifyng about seeing it rendered with the luster and grandeur of CinemaScope.
