Songs Of Mubarakan description

Mubarakan is about a Punjabi wedding set in London.

Karan and Charan (both played by Arjun Kapoor) are twin brothers living in different countries.

Karan is from London and Charan is from Punjab.

Each of their girlfriends (Ileana D'Cruz and Athiya Shetty) are expected to marry the other brother, therefore Karan and Charan must go to their fun loving uncle Kartar Singh (Anil Kapoor) for help.

Will the uncle help his nephews escape marriage or doom them?
