After meeting a scientist Dr. Sathya, played by Anupam Kher, Ravi obtains a drug which cures mental disorders from him and injects Buddhi, leading him to become intelligent.

However, in the process, Buddhi starts to forget his parents and friends, leading to uncontrollable tragic events.

The film was originally planned in 1999 by director Kaushik Roy, who conceptualised the idea from his own child Orko.

Apna Asmaan received mixed reviews from critics, who debated the direction and story, but praised the acting, themes and messages about the parents' overambitious dreams inherited to their children.

One day, Ravi watches an interview of a scientist, Dr. Sathya, who invented a controversial drug called "brain booster", which can cure mental problems.

After winning a mathematics quiz show, Buddhi is given the title of "Aryabhatta" and becomes popular in the media and receives fame as a "mathe-magician" celebrity.
