In the film, you can watch great Amitabh Bachchan as 13 year old boy Auro whose outer appearance looks like 5 times older that his actual age. Auro is a boy suffering from very rarely genetic defect called progeria-like syndrome, which causes accelerated ageing. He is very happy child attached very much with his family. His father is Abhishek Bhacchan who is young politician and mother Vidya Balan who is gynecologist. The movie is all about the unique Father-son relationship which is never depicted on the big screen before. Paa deals with human emotions and sentiments within the family members with the genetic disorder as a back-drop. I would suggest to view this film at least once as the subject is altogether different and the storyline is not the subject of reading rather is a subject of feeling emotions.
