(Ajay Devgan) lives in Mumbai with 14-year old brother Rahul (Dushyant) who
suffers from Cerebral Palsy. Raj spends most of his time taking care of Rahul
due to which, his own life takes a backseat. Rahul is totally dependent on Raj.

their extended family. Suman loves Raj but Raj always shrugs her off, as for him
his life is dedicated to Rahul.
