The music of the film has been composed by A R Rahman. Ada  is the tale of Ayaan, son of a noble human being Anil Anand, and a spiritual mother, Aamina. Ayaan’s gentle world is turned upside down when Anil starts receiving death threats if he goes ahead with his testimony against some criminals.

The murder of his father sets Ayaan on a course of revenge against the criminals of Mumbai, and he becomes a contract killer.

The conflicted character of Ayaan Anand is a modern tragedy as he becomes part of the criminal stream, even as he searches for truth and happiness. Ada is a film of the moment, as it compels one to re-examine the youth-crime phenomenon in a very poignant and freshly-told story.
