Plot

Paa tells the story of an intelligent and witty 13-year-old boy, Auro (Amitabh Bachchan), who suffers from progeria, an extremely rare genetic disorder wherein symptoms resembling aspects of aging are manifested at an early age.[2] Mentally he is 13, very normal, but physically he looks 5 times older. In spite of his condition, Auro is a very happy boy.

Auro lives with his mother Vidya (Vidya Balan), a gynecologist. He is unaware that idealistic young Parliament-member Amol Arte (Abhishek Bachchan) is his father, who had had a relationship with his mother while the two were students at Cambridge University. Amol, is young, progressive and a full of ideals, politician. He is out to prove to the world that 'politics' is not a bad word. He is a man with a mission.

After Arte meets Auro, whom he does not know is his son, at an event at the upscale Prince Edward VII School in Lucknow, the two develop an unlikely and occasionally difficult friendship, to Vidya's dismay. Auro eventually learns the truth, keeping it from Arte as he comes to grips with it himself.

Paa is a 'rare' story about a father-son, son-father relationship. Paa has a loud n clear message for everyone, everywhere in the world, for the change. "Be the change, You want to see"
